James your experience is similar to mine. after a big discrepancy (KICKR 35-40 watts high) I got it pretty close to my SRM w/ multiple spin downs. I also see some drift at the end of workouts and can get it back with an additional spin down. This is all in ERG mode BTW.
What I do, and what you might try, is just leaving your offset from the the end of this workout on your KICKR. When I start the next day's ride, the KICKR actually reads low by a few percent until the unit gets warmed up (or I get to higher wattage, not exactly sure) and then it's right on.
I'd be curious to know what you do/did at the start of the NEXT workout after this one.

Here's a screen shot of what I mention. You can see that at first it's low (my Quarq is low compared to Kickr's Target Power) by about 10-15%. I then do a second spindown at minute 15 or so and, at low intensities, the Quarq essentially mirrors the Kickr target. The yellow power line obviously goes up and down quite a bit but that's pretty normal insofar as power is concerned. I am not sure why on the 4th interval the power dropped a bit (to maybe 2-3% below target) but another spindown during the recovery section got it back to at or just above target power.
