Ah that makes sense Aleman
With regards the left right balance thing it's a bit of a funny one for me. To balance it out are you supposed to try and push harder with the leg that's letting the side down? If I'm at full tilt I'm going as hard as I can so.... but maybe it's more an issue of technique rather than outright power. I know Andy did sessions based around smoothness of pedal stroke on trainerroad last year so maybe he knows a bit more about it.
Maybe it doesn't matter in itself if one leg is working harder than the other but it may show there's an underlying flaw with the smoothness of your pedal stroke.
I did Tommy, TR broke the pedal stroke down to four parts, push over the top, force down, pull back at the bottom of the stroke and lift. I found it really does work in giving a little extra power without depending too much on one muscle group. The race on Tuesday, in the latter part where I was losing form due to fatigue, I forced myself to be more smooth and concentrate alot on form, my power jumped up 15 Watts. I was beginning to pedal square just before
