Someone collated the “best estimates” from the LPSG forum thread “measured porn stars”.
Read there for details on the estimates:

Someone also put those estimates through the CalcSD calculator for the volume measurements further down the same page.

1) You should expand the Visualizer by adding these in a dropdown menu.
2) Also consider allowing 6-8 comparison examples side by side. (choose to auto fill all examples with “top 7 length, girth, or volume” or choose each by name)
3) Also, fix the “volume” calculation, it shows extremely high numbers of valume sizes in that Settings drop down menu (in the thousands of fluid ounces each time I tried it).
4) You could also show data for “between size” data, like what the percentage growth of Length, Girth/Circumference, Volume are from size A to B to C, etc.
By adding in “time to growth” with a variable input for how much time it took to reach that growth point between Size A and B, you could then calculate and estimate of time it would take to reach a Size C with the unknown variable being the amount of TIme. You could also choose the unknown variable to be the unknown size C which would be based soley on the previous sizes/growth/time inputs so it could give you a progressive series of sizes possible after 6-12-24-etc months so the small size differences could be seen to help people realize the amount of time needed to reach those points of diminishing returns for time/effort into the process. You’d have to figure out maybe even “constraints” to be applied if noobie gains were already reached (referencing those 10+ year advanced PE-ers that only squeezed out a small amount more growth, or not, there might be continually growth possible if deloading periods are incorporated or whatever other hypotheses emerge from longer term, more consistent practitioners’ experience).

It would totally be the best of all the penis size and visualizers out there if you did. CalcSD didn’t take up any of these recommendations and just made the slightly less informative “Graph”.

5) Oh, you could apply real population groups from data/wikis. Like half of 7 billion people is male, then continents with applicable race-based data (CalcSD), then major cities, mid-sized, etc. which should be easy since most of that race data per region can be calculated out like seen in justicemap.com (county* data of USA, just extrapolate to major regional race groups and penis study data as a ratio). This would give you a much more region-specific answer in regards to “how many are longer than you out of x-number” since it would be a region (for those that want to know what they’re heading into when they go on vacation or what the competition looks like locally).

The latter part with populations is some extra work (maybe a simplifed version with just country and city and average middle/small city), but seeing how close many really are to regularly over-inflated sizes of the most seen p*rnstars might give some people hope. Collating information into a tutorial on how to best capture your size in photos might be a worthwhile page, too. “All steps of the process of launching your unit into wet orbit.” Something like that.
