One comment here about pool currents. My pool has wall vents that blow out water which circulates and sets up currents. In some lanes I often notice that I need a larger SPL going in one direction than in the other direction, and that is a good indication of currents. If you want to prolong your SG, you should know where the currents are and what direction they flow in!
