Unfortunately, this does not prove ones ironman playtime.
I've reset my account 3 times and each time the "approx time played" didn't reset. Therefore, I assume this is linked to ones account rather than an individual CMDR. Theoretically, one could be on CMDR 1000 & have a massive amount of playtime with 0 insurance claims.
BTW, I'm not saying this applies to you Kenneth.
I think the 0 rebuys is the most important, Time played is a little irrelevant as you can leave your computer on while docked to clock up hours if you so wish, but then your other stats would be weak, # of jumps, distance traveled, kills, infractions, bounty's, highest bounty, scans, materials collected, engineers unlocked, permits unlocked.
i.e.
insurance claims: 0
Time played: 17 years
Number of jumps: 12
Kills: 20
is not a compelling story ^^
point is; in the stats panel you can build up a picture of a CMDR playtime, also if your triple elite rocking around in a G5 engineered Cutter with 0 rebuys that's a bold statement in itself.
it would require self policing, and a decent system could be set up, if its popular FD will develop it, exploration started with the basics, now arguably the most popular PG's in the whole of Elite with CMDRs obeying the rules set in them.
FD do support these smaller groups if they set up, and make some progress and succeed with it, Community driven content has been widely supported - i say dont sit back get in the driving seat and create something if you believe in it.
