i currently string PSG 18 @ 52# in my babolat pure drive 110. i play between 2200-2400 feet, but will be playing a tournament at 5000+ feet next week. are there any rules of thumb or calculations to adjust for elevation changes per 1000 feet increase/decrease, etc.? i'll probably adjust tension to 55# to compensate for the altitude increase if there isn't a formula or advice received to change that plan. thanks for any advice.
