Being a player so far for this campaign and not having to DM (yet) I may have a slightly different perspective.
As we were kicking off PFS in Geelong we were fortunate enough to be able to get a few players along to Arcanacon where we met up with DarkWhite and Fox who were slightly more advanced than we were at the time. This enabled our players to get numerous games under their belts without having to eat any early modules. Due to this none of the Geelong guys had to eat a module for GeeCon. We then followed that by catching up again up with Darkwhite and co. at Conquest. (GO TEAM POWER ATTACK!!!)
Darkwhite on the other hand did not benefit from such mentors.
Hypothetically if Darkwhite, Fox and myself found ourselves at an international event. I would hate for my character to have an advantage over theirs due to the sacrifices they have made to make my groups (and many others I'm sure) experiences more fulfilling.
Dumbing a reward sytem down to protect a campign from a potential exploiter or two robs hardworking DMs like Darkwhite from being able to experience things at the high end.
And besides. Even if a person "eats" a "hard" mod to avoid PC death, (their loss in my opinion) that's still 4-6 players who have experienced it.
My vote would be full gold, full XP, 1 AP for eating (Assuming new mods remain at 1-2 AP)and no special bonuses from the chronicle sheet
I like the concept of a points/incentive sytem for running sessions. The secret mod for 10 sessions run is a good start. How about some form of GM exclusive garment upon reaching a certain milestone (say 30 reported sessions total)
