Decay should be back towards seed score, not just down. If your ZRS is below seed score and you have no recent race data, it should drift back up to the seed score.
Will outdoor activities synced into Zwift via Garmin, Wahoo etc also be used in instances where a Personal Best is set outdoors? Assuming PBs are based on power output and the outdoor ride has power data?
I assume also that someone setting PBs, but is inactive in racing events, that the Floor is what would be moving?
Score should not be decaying while you are active on Zwift. If it is decaying, it should be decaying towards seed, not towards floor.
There are a very large number of racers who basically do no racing outside of ZRL. Or if they do, it’s points races. Are any races other than zRacing changing ZRS now? I know there are a couple, but it seems like races not using ZRS categories don’t affect it, mass start doesn’t affect it, points races don’t affect it, ladder races don’t affect it…..
ZRS needs to be extended to cover at least MOST of racing, it’s only including enough races to be useful for a small subset of racers right now.
Hey @Ryy im presuming you are still in work on Friday west coast time..
Might want to check decay.. Looks like it’s significantly broken. I’m sure others can post the images of 150-200 ZRS score decay reductions..
Does this only apply to a PB? Is that a watts PB or a w/kg PB?
What if someone is at their floor and they set a 5min power 1 watt lower than their 90 day PB. The seed calculated from that effort would be higher than their current score. Would they get moved to the higher value?
So is 30-day highest ZRS pen allocation now live?
@Lee_H Is decay still broken today (I don’t follow anyone to see this myself, but I see some odd ZRS plugin changes for pen E Tiny Races zone one this morning)? Baffling how such a big bug, dropping ZRS by big numbers like 150-200, wasn’t spotted before making it go live!
No. James made a comment recently that he may turn it on for ZHQ Crit Club and Epic Races for October. If it comes to ZRacing that would be after the Zwift Unlocked races are over since there are no ZRacing events for a while after September. Community race operators will supposedly be allowed to request it and the 30 day max number should start showing up on your profile on zwift.com, will come to Companion later.
I think (2+2 could equal 5 here) riders who have gone more than 90 days without an activity, lose their 5 min pb and their floor erodes away.
When decay was turned on as they hadn’t done a ZRS race for 30 days their score decayed to an unknown value as they had no floor..
So riders are seeing 100/200+ point drops in zrs if they have been off the platform all summer.
It’s odd users can spot this within hours of it being released and the professionals whose job it is to implement this stuff completely miss it, or let it pass and think that is appropriate for returning riders.
Like I say, might be 2+2=5 but it looks suspiciously accurate at present.
I haven’t done any ZRS races in quite a while but my score just dropped, after a long time at 504 it suddenly went to 424. Might have to go stomp some ZRS races in my new lower category.
@Ryy Do you have an answer to this please ?
‘I heard rumours that there is a cap on how much the decay can lower your ZRS score. Can you confirm this and how far do you guys allow it to drop ?’
When decay was implemented my ZRS dropped about 16% overnight. I have raced (a little) over the summer but all non-ZRS races. I don’t think any PRs dropped out of the 90-day window in that time (and it was supposed to go to a 365-day window for those without ZRS activity, right?) so I’m going out on a limb and assuming that the decay limit is equal to your floor.
Probably. I’m assuming that it retroactively decayed my score going back to whenever the last ZRS race I did was, which has been quite a while.
Time to race. Go get some.
me Racing Score 317 354Max. @Paul_Southworth @Rhino-Racing someone going to put group at 353zrs ? just for me ?
We would have to rename it to Bath Salts Crit race.
Go do ZRacing on Triple Twist and you might get to 349 whether you like it or not
@Lee_H - Do you have more information about what is not behaving as expected with decay? To clarify, when we enabled decay, it was applied immediately. This means Zwifters that haven’t raced in the past 30+ days in a scored race saw their score decrease to the decayed value immediately starting last Thursday.
