For 7 legged parlay, I would not be $85 usd, that's too much for me, maybe just around 5 to 10 usd as that is just my range.
But you are lucky to win, and maybe you have a bigger budget in gambling that's why even at a parlay, you are confident to bet that high.
Yes very lucky. For me gambling is a place where looking for pleasure, not the full profit, if fully looking for profit we will be encouraged to play unhealthy or out of control and result in losses.
