Strange results for v3.67a

Now not all pairings for v3.67a completed, but after 782 pairings this version get - ~0.4 APS and it's strange, because the change is fix for used data for surfing. Tomcat for a long time use data from two ticks before fire detection for range search. For example, if Tomcat detect a energy drop at 10th tick, then it use for range search data from 8th tick, while, theoretically, enemy uses data from 9th tick for aiming. And v3.67a try to use data from 9th tick. Without success. Anyone has any suggestions why?
