Agreed - we need to move closer to .001 to lose the 1-tic-flip crowd.

Buy 1, sell 2 = 100% profit

Buy 2, sell 3 = 50% profit

Buy 3, sell 4 = 33% profit

Buy 4, sell 5 = 25% profit

Buy 5, sell 6 = 20% profit

Once we get to 5 on the bid and 6 on the ask, where a 1-tic flip gets 'only' 17%, we start to see folks hold for bigger gains.

All in my opinion, of course!
