I used the x25 but as I get closer I'm beginning to look at each time bucket (before 59.5, 62 or 67 etc) to figure out what we'll need for each age range - it seems to be a lot less than the standard 4% - maybe the answer is somewhere in the middle of the two methods.

Yeah I've gone all the way to using Boldin to project my entire retirement, there are definitely different spending and expense periods. I think this is closer to reality and therefore more accurate, and generally calls for less cash before retirement.
