Increasing tension as you go down crosses

IMHO The standard method for stringing crosses creates a stringbed that is consistent when measured by stringbed deflection methods regardless of what linear tension is measured at the very edge of the frame. That tension measurement would be different if you measured at different spots across the racquet, reaching the reference tension nearest the edge next to the tension head. This linear tension difference alternates from one side to the other with each adjacent string, so the stringbed deflection in an area the size of the ball impact would probably be uniform anywhere on the racquet.

I can see your reasoning for doing this for sure. Most of the time if i feel there is a lot of friction in the string bed I'll pull the cross twice, the first time to pull through the friction and the second time to reach reference tension.

That might very well be true, but the method I employ averages the differences in the middle better for each string.

For example, let's assume the ref. tension is #60, the cross tensions may look something like this (starting crosses from right).

60------57 (3lb drop, avg 58.5)
55------60 (5lb drop, avg 57.5)
60------53 (7lb drop, avg 56.5)
51------60 (9lb drop, avg 55.5)
60------49 (11lb drop, avg 54.5)

Totally simplified but you get the point. With mine it looks like this (ramping up ref. tension for each cross):

60------57 (3lb drop, avg 58.5)
56------61 (5lb drop, avg 58.5)
62------55 (7lb drop, avg 58.5)
54------63 (9lb drop, avg 58.5)
64------53 (11lb drop, avg 58.5)

Of course my numbers come out a little different but I hope it's clear what I'm trying to achieve. By gradually increasing the string reference tension with each descending cross, each cross's average tension stays roughly equal. Ideally you'd do it down the entire face of the racquet and I may end up trying that. Currently I just start halfway down.

Of course lots of other variables influence the stringbed tension differences. Different types of strings may have greater or lesser tension drops, so you might have to ramp up ref. tension more for those types of strings, etc.

I think that the drops in tension are actually beneficial to the string bed-- they automatically create a mild proportional situation (mild because as the friction increases, the string shortens). I have a suspicion that these drops in tensions are actually responsible for creating, in part, the feel of the sweetspot.

I guess the big question is: Can you feel a difference, what is that difference, and, if so, have you found it worth the effort?

What about using a 50/50 pattern? Would that at least make the tension differences symmetrical?
Yes that is a good point. Instead of losing tension going down you would lose tension moving away from the middle of the racquet.

I agree and would keep a constant tension.

I've been using this method and the playability is not largely different, however the lower strings do not move around as much and the string-bed just feels less sloppy at the throat.
