Does when you send the score matter with AoBing? aka time taken to play the game?

If you finish the game but wait for a certain amount of time before actually sending the score, is that time considered playing time?

Which is better for earning trophies (safer) ? SSing or AoBing?

I also am having problems using MajinSS (it crashes) but I'm going to try some more troubleshooting before I ask a question about it.
