There might be a difference in batches. I have had both Alpha Crux and Phase ll. Crux lane polished quicker and lost its reaction quicker than Phase for me. The other side if the coin is that lane polish isn't always bad. Best example for me was original Virtual Gravity. Much better ball for me after it lane polished. More recently I had a similar experience with Lucid. Going back a few years, Cell, Infinite One, and Theory were just the opposite. They stopped hitting for me after 30-50 games.
Also, I recently had some experience with the wave machines for oil extraction. Used it on Alpha Crux and IQ tour. In both case immediate improvement was very noticeable, but short lived.
