How accurate is the Trainer Mode?

I've heard the formulas can be as much as 5-10% off, due to manufacturers' variances in the trainers.
these numbers look a little high to me, but at the same time, are within the range. how consistent are the Kurt Kinetic Riad Machines with their formula? Would it be a good idea to calibrate my trainer with a DFPM?

In the iB3 software Trainer section you can tweak the profile if you want. When I first got my KK Pro Trainer I started to mess with it then I realized it just didn't matter. It's very consistent onto itself so there's no issue there. And the relationship between indoor and outdoor wattage has almost no connection so I don't bother trying to make the two match. If tracking TSB you might want to adjust TSS based on perceived exertion but I've found leaving things alone works just fine IMO.

a watt's a watt, right?
I used to do intervals and junk with my Power Tap on the trainer, and it seemed pretty connected to doing it on the pavement....
what do you mean?

Since you know trainers then you know that it takes a lot less time to get worn down as much as being on the road. That's all. Between heat and boredom and the constant effort required at least for me, trainers drain me a lot quicker. Hence a lower TSS score which might not reflect the effort that went into a session. At least that's how I see it and feel it.

gotcha
funny thing is that I find an hour on the trainer at a high wattage+HR easier than on the road
I find HR is higher on the road because my upper body and core are doing work to bear weight and soak up bumps, and things like pavement changes and road undulations make holding a consistent 10w zone harder
trainers, you just start chunkin....
