If calling "approaching" 2,500' above the level is considered excessive, what is considered acceptable?
I usually call about 1 min before reaching the level to allow time to get the call in and receive, hopefully, a clearance for continued descent, before the autopilot starts capturing the level. Thus with a vertical speed of -2,000 fpm, it'd be 2000' above the cleared level.
