After a series of unfortunate choices (5 consecutive losses - possible record??), my credit balance dropped from 125,000+ to 241. Over the next couple of days it bounced back and forth from 500 to 0 to 250 (no bets placed, no postings made). It finally seemed to stabilize at 501. I bet 100 on Drake to cover -9.5 (balance at 401). They covered (601). I have placed no bets since, and made no postings until this one. The next day it shows 500 and stays there. This morning I find it at 150. I don't understand the system, and at this point have lost interest in trying to build it back up if it continues to go backward for no apparent reason. Any answers?
