I like the concept and could see it being a really useful resource, so well done!
My basic feedback;
Design: lots of wasted space in the head and footer, UI & UE is lacking (e.g.- The tables are difficult to navigate as there aren’t dividing lines and the background colour is also white).
Optimization: Looks really good actually, I like the fixed ID column
Functionality: Basic- would be nice to have additional comparison options, such as a ‘difference’ column that gives the +- comparison. Look up and sorting functions is pretty key (discipline, wheel size, sex, etc). I’d add some more parameters. Death by scrolling is not ideal.
I know all of the above will come with time and I don’t mean to be overly critical. I’d be happy to get involved in this project if you need a hand. I’m a BSA with some free time- cokie.stw(at)gmail.com
Edit: I see where your design and some features comes from, hayhub.com. Looks like you’ve used the same template.
