Wow! that worked as well...gosh on a roll..I think we have nearly proven the code!! which is always the hardest part...See how we go with more testers :)
Not 100% I managed to get all your odds working right as the levels go up, it will all need to be checked - but once I get sleep :)
for ibtbattledoughtaker you have no credits left - transfer at least 0.01 Steem to @wizardzap with memo:
Transferred 0.02, let's see if I get 2 credits for it.

Minor Bug Progress % things needs some work...but will think of something there.
Try sending a little steem or SBD if can, lets see what happens. I'll send it back.
Don't send too much though as I haven't test much passed level2 and haven't finished code pas level 5 currently
