James –

Your watts per kilogram is at 2.794 (Not too bad).  It will be even better when you shed those unwanted pounds this winter!  And after you get a full winter program under your belt!
Your LT is 216 watts.  Divide that by your weight, 77.3 kilograms.  You get 2.794.  Your HR at LT is 140.
We will make those numbers better!
