you are looking at what is on grid now.
if grid is split at 600 or smaller and over how many new entries you would get?
how many over 40 race 600 but not F40,same for small bikes.
what is goal of splitting it?
All good questions, don't know how to get the data to project what it might look like if guys who are over 40 but don't bother because they are on smaller bikes might decide to run if they didn't have to go against liter bikes.
Another possibility is that with 5 possible classes to chose from (600 Prod and SB, 750 Prod and SB, F1) the 600's have enough places to run without us needing to create another class for them. If the 600 rider is over 40 they can run 6 classes, 7 if they can make the FP cutoff.
Better question is why split it, I voted to leave it as is. You want to win races you need to run fast laps, this is the AFM after all. The top 20 in 600 superbike showed last weekend that a 600 can run as fast if not faster times than the top 10 in F-40 and most of the liter bikes, so I don't really think it's displacement that is the issue. The guys running in the front of F-40 are just plain fast, regardless of displacement.
F-40 has stepped it up in the last couple of years, 2:00's at Thunderhill just won't cut it. Last race you had to do 1:55 or better to just get into the top 7. However a 600 in the right hands is more than capable of doing way better than 2:00, so I think this is not really something to spend a lot of time on, esp., when the 600's have plenty of classes they can be competitive in if they think they can't be competitive against the liter bikes.
