Sorry for the confusion, yes, increasing the number of payable shifts to more than 10 is what I was talking about. I almost put just "lengthening the shifts", but I added "payable" thinking that would avoid the confusion. Clearly not.

Like the others said, an increase, or decrease won't earn you more, or less. The only value to increasing the number of payable shifts is to see less of those 0 BTC shifts, it's purely superficial. But unless you increase that number to something like 35, then these +90% bad luck streaks are still going to leave you with those 0 BTC shifts.
