Let me know if this makes any sense to you, or if my thinking is flawed. I've strung one of my racquets by the same stringer, same machine at 2different tensions. With the first tension, 54/58 I was hitting long. So I upped the tension to 56/60 and it seems to me like I'm hitting about 2 feet shorter. Is it too simple? or is 1 lb of tension equal to about a foot on the court?
