WELCOME. TO. THE. TEST. VERSION. OF. CALC. S. D. *dancing* *dancing* *dancing* *dancing* Actually, this is what calcSD looked like, more or less, before v1.0 (before I published it on the internet). After I made the new user interface I didn't just want to throw this away, so I made it into a test version. This is also the only page on the site that uses a blue mushroom as its mini-icon instead of a red one.

Explanations for those using this:

1. Mean (SD): The average/mean of the selected study, also its standard deviation.
2. Values: Your measurements. Volume is calculated automagically and assumes you have a perfectly cylindrical member.
3. Percentile: Your percentile relative to others.
4. In a room of n: How many would be bigger than you in a room of n people other than you. You can enter a custom value below.
5. Z-Score: How many standard deviations you are above (or below if negative) the average/mean.
6. Compared: How many times bigger than the average/mean you are.
7. Other/Length: Shows the length to flaccid ratio for the grower/shower classification. I prefer using the volume to measure it instead.
8. Other/Girth: Shows you your approximate diamater (depth and/or width). This assumes the width and the depth are the same, which they probably aren't.
9. Other/Fl. Girth: Shows the flaccid volume. No, I'm not doing percentiles for this, don't even ask.
10. Other/Volume: Shows the volume to flaccid volume ratio for the grower/shower classification.
11. Errors: Gee, I wonder.
