Are you certain that your reach is not too far and that you are sliding up to compensate? Competitive Cyclist calculator is good but it's not the end-all be-all of bike fit.

I set in this order...

Saddle height
Saddle setback
Reach

...and got close enough that a Retul fit only changed 2 things, rotated handlebars ever so slightly and shimmed one of my cleats. I knew going in that the cleat was a problem.
