It was inspired by How long is my schlong? and abovethemeans' volume calculator. The former website, HLiMS for short, had a few issues which I wanted to fix in calcSD, mainly the fact that it looks up percentages in a fixed table for every 0.2 increment (meaning values in between are rounded downwards), but also that it uses outdated data from an old research, Hungfun's Average.
I tried making it as lightweight as possible while still looking modern and having a lot of functionality, but please excuse me for any design flaws, I'm still learning. I value privacy, so absolutely no data is collected when you visit the site or make any calculations in it, at least, none I can control. I have no way to tell how many people, if any, even visited this page.
