I don't rely so much on percentage as I do the actual number.

I can relate to this. I haven't done a field test to see what my TT HR is for a long time, so I'm not completely clear on my HR percentages these days. But, I am getting a pretty good read of how long I can go at various actual HRs, and how they affect me later, etc.

Thanks for your post. Makes a lot of sense.
