Fast Pools

Hello, I have heard people say that some pools are 'fast,' but never really thought too much about it before a recent meet I swam in. Our AZ State Long Course (50m) meets had usually been held at the Phoenix Swim Club, and I competed in several meets there. This year, it was held at the ASU Mona Plummer facility. I know that it is possible for improvement over a year, especially with the coaching staff I'm exposed to, but is it really possible to shed 2 seconds in a 50m ***? Or over 8 seconds in the 200m *** over a year? About 9 seconds in the 800m free... No, I have not (yet) purchased a full-body suit, but have considered that for some time. I have heard that they can make a difference too. I guess I'm just trying to see if I can take the credit as self improvements, or if the ASU pool is significantly 'faster' than the Phoenix Swim Club. Any comments would be most appreciated. Thanks.
