Just built an online fit tool, want some feedback

Hey everyone, long time lurker here. I built a tool to visualize your fit on a given bike, and what effect changing various measurements has on that position. I’d love some testing and feedback if anyone could use something like this.
The project can:
draw a diagram of your various angles (knee, hip, and shoulder) given a set of body measurements plus bike measurements.
Save a default set of body measurements (to avoid needing to add them every time) and add them to your diagram.
Save and edit diagrams per user.
Share uneditable diagrams via link with other users.
Redraw the diagram on the fly based on changes to your measurements.

Future features:
Draw diagrams for road and mtb measurements.
Load preconfigured bike data.
Annotate diagram with arbitrary measurements like a tape measure.
Try it out and let me know what you think. It’s at http://bikefitr.net

Here’s what the result would look like. https://bikefitr.appspot.com/static/sample.png

Replying to myself. Version 2 is done. Now you can choose between tri and road bars, and drops or hoods position.

Heel to cleat measurement: is this tip of cleat, center of cleat? is it to heel center or edge of shoe? Is this measurement for toe overlap.
