A HA!
I haven't been opening the tube ahead of time. I've been letting it open for me. I guess it would make sense that it will mess with the shot. Thanks!
I have been locking the scope while doing the speed test, but taking it off after I check the box. I thought I only needed it to be locked while timing the ship. I should leave it on even after the speed test is over? I always leave it off so I can move the scope around - I suppose it's good that I was never a real captain lol
Thx again for the info people!
