They likely negotiate on a case by case basis and therefore if OP came to the table with prior knowledge of what could they expect, they could better negotiate.

For example, Stripe would obviously prefer a customer that gets to $80k by processing many $5 transactions rather than a few $1000 transactions as they collect 30 cents per transaction. They would also look to see if your transactions are primarily VISA/MC vs AMEX, or CC vs debit since the margins are different on each one.
