The resistance lag comes from the how the trainer works.
The latency lag allegedly comes from the ANT+ transmission.
They would show up in the reporting graphs very differently.
Agreed, but I was reacting to the question of Bluetooth vs. ANT+ latency which has nothing to do with the lag in trainer power response.
As usual.
So the take is that the OP is literally blowing up on rides. The test is 9 Hammers. If you can finish the entire ride on your new numbers and you felt like you went a round with a Sufferlandrian Wildebeest, they are right. If you get to the double hammer and you cannot finish, they are WAY off. If you get to end and you feel like a couple more, you a low. In the last two cases, you need to retest.

Same answer, really. I found that using my trainer on BT, with HR and Cadence on Ant+, gives me the most responsiveness from my trainer and least lag from my HR. BT for my HR and Cadence tends to give me micro dropouts, but not on Ant+. While BT works the best for me with my Trainer with least lag and best responsiveness. Because BT sends data packets more often which works best for the numbers that change the quickest and most often, while Ant+ stays connected better for listening passively to other devices.

No, because you get the same trainer response lag whether you are using ANT+ or BT.
If the delay in ANT+ signal transmission is 5 seconds compared to BT, you would see a corresponding shift in the time the trainer starts and ends its response, compared to the timeline in the workout. For example, the first Violator interval is at 12:17. With a 5 second delay you would see on your power graph that interval start at 12:22. It would end at 12:28 instead of 12:23.
In both cases you would see the same ERG mode death spiral, just at different times in your power graph.

I suspect when you use BT with the trainer, HR and cadence you are getting BT interference, because I never have had such a problem. I used all three on BT for years. That is not a packet frequency or latency issue of BT vs ANT+. Those are different (but related) issues.
When I stopped using my BT HRM because it was flaky, I had BT initial connection problems. I had to disconnect my trainer from SYSTM, end the workout, start the workout again, and reattach the trainer. The reattach often took as long as a minute. When I attached a new ANT+ dongle to use with my Garmin watch HRM, that problem went away immediately.

Sounds like a quantum physics theorem. If you look to find the location of a particle it changes the location of the particle. So you never know where the particle actually is because looking for it makes it move somewhere else.

That would actually be the Observer effect, not the Quantum Uncertainty Principle.

If you do not look, his FTP could be anywhere from 0 to infinity.
If he would do a FF, his wave function would collapse to the measured value. He would collapse too, but that is a separate phenomenon.

But this is what I see. Although if the lag is 5 seconds…and the time the next interval starts and lasts is not a multiple of 5seconds, then it would be offset from the 5sec lag. You’re literally jsut waiting fornthe next signal to ping, so it’s more a lag of UP to 5 sec, rather thqn exactly 5 sec every time. Maybe the lag is 6sec. Whatever it is, it is annoying.
Also, no death spiral on Tacx trainers. That was a Wahoo quirk

I never saw that delay when I used ANT+.
You can get a death spiral on a Tacx trainer. I once experimented with doing some Violator intervals in ERG mode. It was not pretty.
