SF matches scheduling...

Semis will be played at 3PM and 7PM local time...
I think it would be great help for Novak to play against Zverev in the evening... Ball will be slightly slower and serve a little less effective...
In the so close matchup, slight differences can mean a lot... Example was FO SF where late start vastly helped Novak against Nadal...

Hope Novak - Zverev match will be scheduled at 7PM, which is logical, as better players are involved, and Med and AAF had more time to rest...

I think faster the better for novak.
Because Zverev is younger unlike nadal

It will almost definitely be scheduled for the evening. But I don't think the margins will be so thin that a slight drop of court speed will affect play significantly. If Zverev's serve is firing, it'll be a great advantage for him in these conditions. If it doesn't, he's likely screwed.

They better schedule the Djokovic match to fit the european time zone :D :D That used to be the case in the 2000s, in the latter stages of the tournament.

Zverev/Djokovic will be at 7 pm, there is no debate.
1) At this stage of their careers, Djokovic > Medvedev and Zverev > Auger-Aliassime
2) Djokovic/Zverev played the QF 1 day after Medvedev/Auger-Aliassime, they have to be scheduled in 2nd or it would clearly favor the winner of Medvedev/Auger-Aliassime for the final

The only reason Djokovic/Nishikori was a day match was because Sock is American.

When people in the sport talk about “heavy” playing conditions, humidity is the atmospheric variable they mention most often. It comes up during rainy weather like at this year’s Roland Garros, in the sauna-like conditions that often prevail on the US east coast during the hardcourt season, and has even been blamed for slowing down play when the roof closes at Wimbledon. Conversely, one popular justification for the widespread belief that balls tend to fly further than normal at Indian Wells is the dry desert air.

There are two problems with such theories. Most importantly, they’re backwards. Contrary to common intuition, humid air is less dense than dry air, and therefore creates less drag on a ball. This is a consequence of the ideal gas law, which implies that at a given pressure and temperature, a given volume of any gas contains the same number of molecules. Dry air consists almost entirely of nitrogen molecules (N2, molecular weight 28) and oxygen molecules (O2, molecular weight 32). Diluting it with molecules of water vapor (H2O, molecular weight 18) makes it lighter.

The other problem with blaming humidity for slowing down or speeding up play is that, in the conditions under which most tennis matches are played, the effect of humidity on air density is very small. At 70°F (21°C), a change in the humidity from 0% to 100% decreases the air density by a mere 1%, which increases the speed at which a fast groundstroke arrives at the opposite baseline by less than 0.3 mph (0.5 km/h).

At very high temperatures, the effect is larger because hot air at 100% humidity holds more water than cooler air at 100% humidity. But heat combined with high humidity is so hard on the human body that WTA rules, at least, require suspension of play under such conditions (see below).

The reason humid air feels heavy to our senses isn’t because of its density or viscosity—it’s because the more water is already in the air, the less sweat evaporates from our skin. That forces our bodies to sweat harder and do more work to keep cool, leaving less energy available for athletic performance. Taken to the extreme, it causes dehydration and excess body temperature, which can cause the body’s mechanisms to malfunction altogether.

Humidity does have some effect on the surface characteristics and mass of the ball, as well as the air density, but these effects turn out to be very small and largely cancel each other out. More on this later.

Wrong. That has never been the case. The marquee matches have always started in the late evening.
Djoker match will begin no earlier than 8:00 p.m. In America, we call this Prime Time.
That would be 1:00 a.m. in your London.

And 4:30 my time:laughing:
What if the first semi goes 5?!
Do they start the second one right after the first one or there would be 30-60 min break?!

I have two questions: who exactly gets to decide who goes first? And is there a process about it, such as who has played more at night already, or whatever? Or is it a coin toss? I would prefer Zverev-Djokovic be the day match, and Medvedev-Auger-Aliassime be the night match, esp. since Med played his last match during the day, and Djokovic played his at night, but whichever - just hoping the results are what I would like to see happen, and time will tell..

It is the same schedule that is kept for the whole tournament, it works this way for every tournament. The only thing that seems arbitrary is which half of the draw is going to be the first to play, but basically : play first day of the tournament = play on the first semi

That's true but it does not matter anyway, IMHO (revenge mode is on).

Actually some tournaments don't follow that script... I can't give examples right now, but I'm sure because Novak was screwed many times that way, having less time to prepare for the match...

I'm very interested if you can remember any example because I have difficulties to believe that, especially considering slams.

Found one...

Rome 2021:
Novak started tournament May 11th
Rafa started tournament May 12th
It reversed so Novak played evening semi, while Nadal played afternoon semi... Off course Novak finished lately and had nothing left in the final... And it wasn't first time in Rome similar to happen...

By the way in Rome it's huge advantage to play first semi, and off course Novak suffered schedule all the time, Nadal on contrary enjoyed nice schedule...

I made thread some time ago on that, will try to find...

Serve is much MORE effective at night. Any infinitesimal change in velocity is insignificant compared to the dramatic reduction in light at night, daylight being MANY times brighter than even the best artificial light, so returning serve is that much more difficult under the lights at night.

Of course.

And the tour apparently wasn't dead AF during Rome also, because Opelka, Shapovalov and Zverev make up what is one of the toughest draws possible. A strong solid win for the champion that week.

Alright, thanks. Rome is pretty sheetty with their schedule, every year it annoys me to see that second semi played at night.

Anyone knows the schedule of the Final?

It has always been 4 p.m (in NY) in my memories. But I am reading people saying it will be at 7 p.m this year.
Assuming the final is Djokovic-Medvedev, I could change the outcome a lot. I don't know if Zverev/Medvedev prefer playing at day or night but it's clear Djokovic prefers night sessions.

It is not clear Djoker prefers the night session against Zverev.

But it is a moot point as there is no other choice. Scheduling Med vs FAA at night would draw zero viewers.

Zverev is taller and beat Novak at the Olympics in very hot conditions. So I think evening benefits Novak.

The difference a lively bounce makes on the serve is also pretty significant and it will make Zverev's serve a bit less potent.

And us folks in Australia have to stay up all the time for any ATP tournament outside Australia - which is almost every single one :eek: .
does your government allow you to stay up late? or is there a curfew you guys have to follow from your commanders?

Two factors. He played the late QF, so it's only fair that he get the late SF. The match with more TV drawing power is always scheduled later. At '18 Wimbledon, Djokovic-Nadal was 2nd, after the interminable Anderson-Isner.
