I Calibrate after line-up 3 times inbound, 10 seconds each, before drop.
Also calibrate after drop to double check that speed did not change.
I Always approach, calibrate and drop at full throttle. Is one less variable to worry about. Also go "auto pilot-level" well in advance of calibration so altitude variation is a non-factor.
Prior to this problem, I always hit my intended target from 20k or higher.
Something has changed.
Is it possible that the calibration text (yellow instructions) which yield "Easy-Cal" info are now obsolete and the old "cross-hairs on a fixed object" are now required again ??
