There's nothing mysterious about it. If something is "full" pay, then there is no paying more than that. IE, the best paying game on a vp machine manufacturer's menu.

I twice saw Elliott Frome playing vp in LV, once at the Gold Coast and once at the Rio after a GT get together. Both times he was playing nickels. Yes Grochowski calls himself one of the "experts" but all he's ever done is quote what Lenny Frome, Dan Paymar, and other similar types have been saying for years....except the one important fact that Lenny told my book publisher that he gave up playing advantage vp because he could not win.
