Take Schedule A, 20%/10% schedule. B is a rip, it pays 21% then 11% which is a little higher, BUT, it does not pay on the premium increases, while A does. So over the years, say the
PPO 2000 goes from $200 a month to $300 a month, on B you get 11% of the original $200, on A you get 10% of the increased $300 premium.
B is intended for those who plan to move clients from carrier to carrier a lot and want the slightly enhanced 1st year commission.
