How common is 300w for an hour?

If my power meter reads 300 or 305 or 280 is totally irrelevant as long as it's consistently calibrated. Calibrate it against a known weight and as long as it's consistent you set your zones and go.

If you're using a power meter to "track fitness", though, maybe this is all beyond your training requirements, anyway.

sort of. Teton Rider used to argue in here about having your weight down to 10 grams. The 25 kg weight someone is using might be + or -, but as long as they keep using the same weight if it's 300 or 305 watts it's a bit of a shrug.

My trainer records power, GPS estimates calories burned. Those factors averaged over several workouts along with time and average speed of a given distance all factor into my fitness tracking. Now on race day, I check my resting pulse as it indicates whether I'll have a good day or not. I'd say the resting pulse is vital. Has been a good indicator for all the years I've raced.

In addition, because they're accurate, I know that my smart trainer is not (and reads about 10% less). If I were trying to train by the numbers from my smart trainer, or use it for racing on Zwift, I'd have some serious frustration.
The point is, accuracy matters, otherwise the data from other powermeters is pretty worthless.

Can't imagine having three different brands of power meters, or them being accurate to one another but I guess it depends what they are. I've had a handful or SRMs over the years. I've got 11 or 12 years of data I'm pretty good with.

I currently have three different different power meters. In the past I've had several more. That they're all accurate is important, lest I have to start over with data accumulation and analysis for each and every one.
In addition, because they're accurate, I know that my smart trainer is not (and reads about 10% less). If I were trying to train by the numbers from my smart trainer, or use it for racing on Zwift, I'd have some serious frustration.

I'm finally ready to retire my ptab hub... I've had three now and no other meters to date. Total boomer status, I know.
I'm thinking of doing the Favero pedals, they seem pretty cool.

Yes, well, that's the entire point of accuracy! That's what I'm saying.

I have looked at those pedals a dozen times and every time I convince myself to get them I think back to using those awful cleats (when I tried to go weightweenie with some Xpedos) and I abandon it. I just can't give up my SPD-SL cleats.

What's wrong with powertap hubs? I really like mine, and it's how I race on zwift (on rollers - with a fork stand at the moment).

I had a second PT hub on a carbon tubular but cracked the rim and didn't want to rebuild it at the time so I just sold it. Crank based is just easier to deal with that this point. Plus, when I did race with it in the past, I once had a flat early on in a race and had to change my rear wheel and lost my data. A bit silly, but also a bit annoying.
I also can't use my PT on my trainer, and as mentioned, since my trainer reads so low, I have to use my Quarq to have accurate power data.

It seems you're saying you don't care about accuracy as long as you have consistency because you have 12-13 years worth of data using the same brand of powermeters.
Yet you apparently also calibrate your powermeter to a given weight, ensuring their consistency, yet also ensuring their accuracy... so, it just sounds like you're contradicting yourself.
In any case, my powermeters meet my needs, and the statement this entire tangent rests on is by a guy who doesn't even train with power, so a bit of a derailment.

why is everyone always wrong, but you?
no contradiction at all.
It is not

It is not not accuracy. It is consistency. I do not know with precision what my weight is, or even what a slight derivation means. I know my 300 is 300 time and time again. I do not know that my 300 is your 300, not in any way shape or form does it matter.

Which is why accuracy is important. That you seemingly don't care about that doesn't change it. I care about it. Lots of other people that use multiple powermeters care about it. The people that MAKE powermeters care about it.
If I'm wrong, so is the entire industry...
