The main problem, and I see this a lot in this type of analysis, is it completely takes attraction out of the equation. It is assumed that all men are attracted to all women, and vice versa. In reality, if you're not attracted to someone, they are not in your pool, regardless of any other factors.
Any such analysis must be conducted on a per-sex basis as the game is completely different for men and women. In fact, it's debatable whether the creepiness rule applies to older women, or to women at all for that matter.
To do this properly for men, the number of available older women needs to be heavily attenuated. According to this, 60 year old women are in the dating pool for 35 year old men. How many 60 year old women do you really think a 35 year old man will find attractive? A vanishingly small number. Conversely, men find the women on the bottom end of their creepiness band disproportionately attractive. But not enough to balance it out. I suspect it would be more realistic to simply rule out all older women.
For women, attraction is different. Women do not have a preference for younger men. In fact, the opposite would seem to be true, especially since women do have a preference for wealth, stability and status. So, using the same example of a 30 year old woman, think about the limits of the non-creepy dating pool. How many 25 year old men will be attractive to her? Not many. But, equally, how many 60 year old men will be attractive to her? Also not many. However, it is probably also the case that not many men in general are attractive to her.
There are so many other confounding factors. Like, for example, the fact that women can't do much to change their level of attractiveness, they're either attractive without trying, or they're not, while for men it's necessary, and often sufficient, to build attraction through hard work (similar to how male in other species do courtship displays).
I find the reluctance to take attraction into account to be, at best, wishful thinking and, at worst, delusion. It makes any analysis like this, frankly, ridiculous.
