1. Anything written 10 years ago in LASORS is no longer valid.
2. The ONLY way to gain credit for chock-to-chock time is to.....
KEEP 2 LOGBOOKS!!!.
One military, with sortie details logged under military requirements and the other civil, with flight time logged in accordance with civil practices.
Not very difficult, really.
Merely adding 10 min to each flight without any evidence would be quite risky - you would in any case be required to submit all personal flying logbooks for licence issue.
'Parker Pen' time has caught out certain military pilots in the past, so unless you do as I've recommended for years now and keep 2 logbooks, you could find yourself in the poo if you pad out your military time without any associated log book entries.
