Friend of mine just tested it a bit. It seems to be affected by 3rd Party supplier. I used i.icu to get the workout into zwift. Can anyone of u confirm this as well?
Someone mentioned workouts imported from TP would keep the exact wattage targets, I have not personally tried this however.
Interesting, I’m importing using .zwo files from FinalSurge.
This is all a bit strange and the implication seems to be that the issue is with the workout builder that Zwift provides, and that it’s their builder software that is embedding rounded target values in the actual zwo files. So, there’s really no way to ‘stop the rounding’ without rebuilding any and all existing workout files?
My intervals.icu workout had odd number targets for intervals, but the ramp increase was either 3 or 4 watts every 15 seconds for my specific ramp interval over a single long continuous ramp.
Sounds like they got rid of the rounding with the announcement about TrainerRoad integration
I guess we need shooj to confirm if it’s just for the imported workouts (similar to before), or if it’s changed across the board. The initial comment just mentions TR workouts…
“Zwift has enabled specific power targets for workouts pulled from TrainerRoad, so you can stick directly to the plan. No more 5 watt rounding!”
FWIW, I tried this tool as well, but the results came in 5w rounded. And a 30 second ramp from 85 to 170w, started at 85w, ran for 15 seconds, then went to 130w for the balance 15 seconds (of course never getting to 170w)

So no luck there. Interesting mention on TR workouts. It really does sound like this fix has to rely on the workout building software, and not the game itself.
Opening a test workout in Notepad, this seems like the only code there is. These percent values seem correct to yield the odd number of watts I entered to yield a target that wasn’t rounded to 5 (eg. 108 vs 112 watts). However, both instance in game show 110w. I’m curious what opening a new TR workout file in Notepad shows instead?
The same:
There’s something going on! As we know, Zwift cannot afford a secondary server for testing and QA 
<Warmup Duration="180" PowerLow="0.25" PowerHigh="0.354" pace="0"/>
<FreeRide Duration="60" FlatRoad="0"/>
<Ramp Duration="180" PowerLow="0.33" PowerHigh="0.39" pace="0"/>
<Warmup Duration="300" PowerLow="0.25" PowerHigh="0.478" pace="0"/>
<SteadyState show_avg="1" Power="0.625" Duration="1200"/>
<IntervalsT OnPower="1.250" OffPower="0.556" show_avg="1" Repeat="12" OffDuration="20" OnDuration="30">
<textevent message="12x 12x"/>
</IntervalsT>
Similar with 2 differences.
The use in your example of addition of show_avg=“1” and in a steady state, there’s no “pace="0"” in your example.
Looking at a ramp string OTOH in a Zwift-created workout I have, there is no “pace=0” portion in the my wko file, while your example has this.
I’m far from knowing anything about programming, and no idea if these things are at all of any importance.
Wow, they’re selling their double paying trainerroad people a feature their own community is asking for since years

Easy enough apparently. When will it be applied to all workouts? Or is that an @evan-zwift question?
You could join the Saturday joint CEO ride and ask there (event ID 4801567) 
Using TrainerRoad sync today, no rounding on watts. However, list of upcoming intervals in companion app was rounded (though watts for current interval was not rounded). Companion app v 3.66.0, last updated 24 Jan so I guess next update will catch it.
Looks like we’re getting the standard ZHQ-non-response here, @Eric-Schlange-ZI can you get an answer on this?
Can someone who has a TR workout imported to Zwift that does not round the watts in the workout post the full text from the .zwo here?
I did my first one yesterday, and the watts were not rounded to the nearest 5. (I didn’t open ZC, so I’m not sure if it did the rounding there, as some have said.) I am running Zwift on an iPad, though, so I’m guessing I can’t actually get a .zwo file. (I don’t have Zwift installed on any PC or Mac.)
