Zwift is not smoothly ramping up the power on my Tacx Neo - as it happens e.g. on Trainerroad. Instead of smoothly ramping it up with +1W to +3W increments, it jumps in 30W increments for one minute ramp needles, and it never reaches set power peak.
Thanks! Similar situation for me when the ramp is 5min long; however, dramatic different situation when ramp is only a minute, and power is ramped up from 150W to 400W.
I can see in the workout that Zwift is adding +30W increments, so it’s not related to the smarttrainer. No real triangle pattern for the shorter ramps at the end. Also, Zwift is only ramping up to 400W for the last second, leaving the max power of the ramp at 370W effectively
Having issues with ramp workouts as well, 30 second ramps are just unusable at all, since half of the time it remains on the starting wattage, it increases a bit at 15 seconds and then for 1 second we get 3/4 wattage, never achieving the target watts.
Is there any way to get zwift to do more incremental steps? Did this ever get fixed?
I see there are other threads, but none of them have a clear solution (can’t include links in my post apparently)
Why are you leaning towards that conclusion?
In the video I’m not able to send, you can see the target wattage not moving during the workout (when it does change, the trainer follows through) so I would say it seems like Zwift is not changing the workout wattage.
(Can’t test things right now, will try later on today)
This information is new since I did not see the video. But if the power wattage is not changing then I would assume there is a problem with the way intervals create the workout.
Yes, it seems to be the same issue, no update at all of wattage for large lengths of time (20 and 30 seconds as described in the thread).
Seems like this is a bug. If Zwift allows configuration of 30 second blocks, it should smooth the target wattage over that time instead of every 15 or 20 seconds.
Yes, and seems maybe also partly related to relatively recent change that was made where workout wattage jumps have to be rounded to 5 watt increments when it used to be single watts. So if a 15 second, 100 watt ramp needs an approximate 6.667 watt increase per second – not sure how this could/couldn’t be handled.
@DavidP maybe could weigh in what’s behind some of this?
I’m not aware of any changes in this area, and it’s definitely not my department.
I think it’s publicly known that previous Elite trainer models like the Direto and the Suito might take a bit of time to respond to changes when in ERG mode, so when doing short intervals it might lead to this delayed response.
It is not the trainer delay since the game itself is not updating the target for 15 seconds. Once the ramp ends and the 2 second high watt step begins, the resistance is felt almost immediately. Same with the 15-second mark watt increase during the ramp up - zwift updates the target power and I feel it at once.
I was able to test this in two different ways: with this file you supplied and with a similar one that I created in the Zwift editor. Same behaviour as the Intervals-generated workout: watts are updated on the 15 second mark only.
