Yep Lisa has great breast but also DMD breast are great to. Lisa has C's and DMD has DD's.
My personal likes are between B's and D's.
What was found just by a quick search.
See problem with that is there's no way in hell only 32.7% of men find medium premium. That type of number could be 32% of men prefer medium over other sizes but that doesn't mean that's all they like. If I had to rate my favourite sizes it'd go tiny>massive>small>large>medium. I like sizes in the extremes on both ends but tiny tits are my favourites, still think medium sized tits are great. Just because medium sizes are the overall favourite doesn't mean they're the only ones liked.
The other link you posted while it is incredibly wordy to the point it's a pain in the ass to read it still shows that large tits are quite attractive among the unrestricted population. Given that this is a smut site and no matter how much we dress up our opinions with an appreciation for the literary aspects we're mostly all here to jerk off at the end of the day. I'd suspect most people on this site would lean closer towards the unrestricted socio-sexuality side of the the scale. So larger breast sizes would still likely be popular even if not favourited amongst your typical f95 coomer, and D cups would likely be slightly more popular than C cups.
Lastly developers don't need to aim for only the most popular body types. If they did then there's be no variety and impossible amounts of competition. Making LI's with proportions out of the average favourite might cut down on the potential player base, but it'll also cut down on the potential competition. Marketing to half the demographic is worth it if there's only a quarter the competition.
