I noticed that when it came to size measurements, sizesurvey.com gave two slightly different measurements on it’s site.
one placed girth at 5 inches yet another table placed the size at 5.1 inches.
when it came to length, one table placed length at 6.4 inches, while another one placed it at 6.3 inches.
the difference was between the table of mean sizes and the table showing percentiles.
small differences, but still, i was wondering why they were different at all.
