I don't see what's contradictory, though. Feel free to tell me. Here's what I see re-reading my sentences:
1) There's only a one mile difference in average speed between a 44 and 46 chainring turning the cranks at the same speed.
2) Frank told us his speed is about the same with both chainrings, so he's using about the same rpm with two chainrings.
At the risk of overcomplicating things, Frank apparently thought just changing chainrings would make him faster.
