Well, to be fair you have gone a bit further than "just" saying that when you quite confidently said @CXRAndy was "wrong" to count his turbo miles.I occasionally use a spin bike and a Wattbike weekly too. Riding on zwift doesnt make me think automatically I should be counting milage just because I can. I'm just saying why I don't count milage on a static bike and why. That's what we're talking about here right....?
And whilst everyone I've seen on here saying they do count turbo miles are meaning Zwift (or similar) miles on a smart trainer, you've brought up spin bikes which I don't think we were talking about actually (as I explained in my last post). To be clear, I can see a good reason why people might include Zwift miles on a smart turbo trainer, but I wouldn't lump in ANY form of static or spin bike to that (I don't even know how spinning sessions would calculate or record "miles" to be honest?)
I don't actually think about adding Zwift miles to my personal total by the way, it's just done automatically by Strava which I use to log all my rides - although you can easily split them out as they're recorded as virtual rides. It's then just data, to be used by people however it best suits them personally. Of course miles done on a turbo aren't the same as those done on the road, but then neither are miles done on a mountain bike. But if different types of miles make up your annual total and that means something to you then I don't see the problem.
That's just fine if you don't want to count miles you do on Zwift. I don't think you're wrong to not include them for yourself, but I do think you're wrong to tell other people they're wrong to do so.
