I’m talking maximum, not average. Also, it depends on transaction size; there really is no true transactions-per-second figure for Bitcoin. On top of that it depends on wallet software, too — most of which aren’t yet ready to benefit from the recent SegWit protocol upgrade (which increases TPS somewhat).

In other words: 10 TPS is possible, but this assumes 1) taking advantage of SegWit and 2) a simple transfer from one account (input) to two accounts (destination+change output).
