Ok, so I'm very new to this (no laughing please)

I followed the Hunter Allen 'beginner to intermediate' 20min TT test process, no problem there. IDT made it surprisingly easy
Problems arise when I put the info into the training programme I'm using, www.2peak.com.
It formulates based on the 3, 12, 30mins etc points typically used
Basically the number where all approx 15 watts to high.
Needless to say I buckled myself trying to ride to the Watts given in the first two rides, before realizing that HR / Watts should match up, and they definitely now did not.
I've made steady manual corrections, and am now back on track, but wanted to hear peoples thoughts... Is it normal to experience this?
