Thanks for your opinions and estimations. Actually i don't see a way to miss 3 treasures in one run. I just wanted to mention, that 3 of them have the potential to get missed, so you get only 2 or 3 treasures in one run AND that's the difference to intermediate run, cause there you have a 100% of getting all 3 chests. I will try out the intermediate run today in the evening with 200+ stamina and will let you know the results. Afterwards you can thank me and grind the intermediate run from now on until doomsday xD

4 runs, 2 times 2 gold chest, 2 time 2 gold chests - no gold dragon. maybe bad luck - but I'm also back to 80s run.
