I've decided that I don't want to play the final events in the package, or that if I do decide to, that I'll do so on my own action. Refunds will be issued swiftly.
Remaining buyins: 3 events = 82*3 =246. Of the 246, I sold 61%, therefore 246*0.61=150.6 sold. 150.6*1.09 markup= 164.15 that needs to be refunded.
Refunds were calculated using % bought of 246 (the remaining buy in for the 3 events) * markup, therefore 1% refund = (246/100)*1.09 = 2.68
