This is the opposite of the other answer given above. If someone goes away and has no hard efforts for over 90 days you are saying their floor will decay to zero? That will result in the same issue every CE ZRacing race has.

If we donât have quality 90 day power data for a Zwifter, they will not be able to sign up for a racing score race at all until they do other activities to build up their power profile. In this instance, the following will display when trying to sign up.
As long as youâre riding on Zwift regularly, but not racing, your score will not decay to 0.

Define quality power data please⌠Do you mean maximal efforts?
With stage races (FRR, CT, Hisp,etc) how will this work mid race upgrades. How is the final GC is added into score? With most zwift races that favor sprinters. It makes more of them cat A based on demograhics and amount of races on zwift but in stage races the all rounders, climbers, and TT people will drop them and scoring for each group will be a mess or they do not show which lowers race score.
I wonât share the full details of the model here, but as you participate in test events and get a feel for things, please let us know if you have any feedback! We built the system to be tune-able in a number of ways, so weâre ready to make adjustments as the feedback rolls in. Now that the seed scores are visible and event sign ups are available, we would love to see any feedback related to those elements.

Great question - Weâre working through the details of GC/stage races still, more to come.

Maybe rate the stage races differently based on type on race and lenght. Lowest level the upcoming sisu tour as it is between zrl/weekly series and full stage race or just a weekend. Then middle level the one week races which 3 of FRR races and some of CT. Then highest level grand tour/multi week races (FRR world tour, CT pink, yellow, red). Just an idea.

This is going to be the exact same big problem with CE events all over again. The floor needs to decay over a year not a season. With CE if you did ANY ride you could come back from months off, enter D, and completely blow up the race.

849.99 seems to be the max. If we consider that the initial scores are based of 1min and 10min power at the moment and that one of the top ranked on ZwiftPower has a quite impressive 5.9w/kg for 20 minutes (at only 128bpm) it would seem that Zwift has put a cap on the seed score to avoid any, letâs say, exceptional outliers.

Up next: an algorithm to detect supra-human performances
It only took Strava a decade to figure out and Zwift is coming up on that mark
only 128bpm just think what is w/kg was be if he try harder haha
Any idea if the categories still kind of represent A-E. In the future events I can see the pens split like 0-225, 225-400, 400-575, 575-725, 725-1000.
My score is 395.51 and I was in D before, but quite decent D (mostly podium in Ds and started doing C races lately - landing in the middleish during the peak times)
But overall Iâm quite excited for this.

This is going to be ce all over again by the sounds, zero transparency
finally in a fairer category ?
I hope
Thank you to everyone at Zwift who has worked hard to get this out. Clearly a period of testing and tweaking will be needed, as seems to be planned. But hopefully ZRS will improve over time and become something a million times better than the current w/kg system.

If the mechanics are set up well enough, they can be very transparent about how it works without risking people gaming the system. At the moment itâs very hard to tell if itâs working properly when they donât tell you how it works.
Already, looking at the entries on zwiftracing.app there are some surprisingly big vELO spreads in some of the pens.
But as the seed score includes 30s power, and hopefully theyâve also include a similar mechanism as zwiftracing.app requiring a certain level of effort before a bad result drops you down, it should then be very difficult to both sandbag and win.
There was some mention from ZHQ staff in the Zwift labs clubâs chat that the full technical formula is going to be shared once it (racing score) is widely rolled out - just not during this initial testing phase of labs races (in case the model needs tweaking).
@shooj not sure if you already got this feedback but it looks like something is wrong with HIGH and LOW-End events at 17:10UTC.
It wonât let me signup to any of High-End Pens 
I can signup to higher pens than Recommended in Low-End
I have done a quick research and i think my Score will be around 650 when i get back from riding outside

This was done deliberately according to the ZHQ in the club chat (anyone under 550 will be prevented from joining the high events and getting a ânasty shockâ).

ZwiftPower says your Zwift racing score is 367.87 so thereâs absolutely nothing wrong with the events.
Although it does show how someone who hasnât ridden on Zwift for 3 months (last event on ZP for Dejan was 13 March) might have a less than accurate score
