I think having the matches on all sorts of random days is silly, but that's my opinion.
No, it's not silly. It's quite sensible.
The various flights around here are not the same size. There are way more 3.0 women than 4.0 women, for instance. If you decide that 3.0 women always play on Wednesdays and 4.0 women always play on Fridays, you will have two problems.
First, there are not enough indoor courts to accommodate all of the 3.0 matches that would need to be played on Wednesdays.
Second, courts will sit idle on Fridays because there are not enough 4.0 women to fill them.
In addition, mixing things up guarantees that every team, regardless of gender or level, shares the pain. The "pain" I am referring to is the matches in distant locations and odd-ball times. The matches that are least popular are Saturday nights at 9 pm, and also 7 pm weeknight matches far away (because the traffic getting there is so bad). We also recently had a match at 10:00 am on Sunday morning, which is yet another kind of pain.
I actually think a system of having matches be spread around on different days and times is much better. Everyone has different scheduling challenges. For me, I would rather play a match from 9-11 pm than 7-9 pm on a weeknight because it is easier on my family; others feel exactly the opposite. Also, there are some people who are simply unavailable on certain days of the week. If the league decreed that 3.5 women had to play Saturdays, I know one woman who couldn't play at all because of her soccer coaching obligations. Nor could people with religious restrictions on the Sabbath.
So there are lots of good reasons why leagues do it the way my league does, and it is not at all "silly."
The leagues view on it is "it allows more people to play", but does it? It doesnt if half the time they end up being unavailable because they've likely made other plans on certain days of the week.
Yes, it does allow more people to play, for the reasons I explained above.
If you want to play, you have to look at the season schedule and try to plan other obligations around your tennis. At least then *you* are deciding how much of a priority your tennis should be. In contrast, if the league decrees that you Shall Play On Thursday Evenings, then the player may have his or her hands tied.
(like weekends which seem to be really hard for a lot of people in the summer, people work 5 days a week and they likely made plans for familytime on the weekend, where a weeknight isnt such a big deal)
(what it really does is it facilitates more people registering for your team so the USTA makes more $$$)
Weeknights are a big deal for some people and not for others. Anyone with spouse, family, job and tennis will understand just how tricky the juggling is. The last thing folks like me need is the league decreeing that henceforth 3.5 women will all have to play on Monday nights.
