What has watts per kilo got to do with it?
W/kg has everything to do with it, I don’t understand what you mean?
Almost everything about cycling is down to power to weight ratio. and in the Zwift game, it is EVERYTHING.
People cheat on their weight and blame zpower. The smart trainer people do the same.
I agree, and lets be fair, If a cheaters gonna purposefully cheat, they can also do this with a powermeter.
W p kg is all about what weight you say you are. It becomes a meaningless contribution to the problem. If I weighed 70 kgs I’d never raise a sweat on the bike. Wkg ppfft.
Your weight in the game has a massive effect on your speed for a given power, and to a lesser degree an effect on the amount of work (watts) you have to do to keep up, descend and sizeable effect on your ability to climb fast. This is all also true in the real world.
Why do you think you’d never break out into a sweat if you weighed 70kg’s ? didnt understand that one.
I see them coming past at 4 wpg and when I look at their data they are doing less than 200 watts.
4w/kg @ 200w is a 50kg rider. As you say, clearly could be suspect weight, though also could be a good quality junior rider, and a mid cat 2 racer can hold that (4w/kg) for 20 minutes or so
For example, I weigh 80.5kg and can hold 4.x w/kg for 20 minutes. obviously I’m not kicking out 200w in order to achieve this.
So unfortunately this is pretty much how cycling works, power counts in your favour, weight counts against you.
All I’m trying to say is that PtW ratio, (W/kg) is the driving force in cycling just as it is in any speed based motor sport.
So far on zwift my 9 seconds over 1000w is all I can go. 10 seconds over 997. My weight is 102 kgs, so I am consistently over 9 per kg on sprints. 5 minutes at 570 + and I know I am getting short changed due to calibration.
You don’t say how this compares with your powertap, so I can only say that at 102kg’s those numbers don’t get you very far up the Coggan chart. That not meant to be disrespectful or rude, its just physics (I used to weigh 101kg’s 4 years ago & was producing less power )
And if you have a ‘correctly calibrated zpower’ inside it should correlate to your outside powertap. Otherwise its not calibrated at all. And yes my powertap is calibrated accurately.
Indeed it should. How does the powertap compare to the numbers zpower is giving you at the same time?. ie, if you have a powertap, why are you using zpower? none of my business, sorry.
Out of interest, I tried Zpower a while back (scroll way back somewhere much earlier in this thread.) on my Elite novo mag force trainer… power on Zpower was down by around 30w at most speeds IIRC when compared to my Riken PM.
I took a beating & I didn’t like it!
