Both the 4iiii and Stages dual-leg PMs fit the bill.

Hmm. Garmin Connect tells me I'm on the latest version (3.30), but I don't see that option when I calibrate!
Which powermeter are you using as auto zero is not an option for all powermeters (ex. Powertap hubs).

What's the right numbers though? If that's the only power meter you have then as long as it's consistent ie the effort you're putting out is giving you an expected power output similar to what you've had before for the same perceived effort then it's still accurate. If you use different power meters then you can compare to some degree but if you need to check it's still calibrated as when it was new then you'd probably need it to go back to the factory for them to check unless you have accurate means of doing that. But that's a whole new discussion out of my knowledge base. Only if it starts giving some odd numbers compared to previous similar efforts would I be suspicious of accuracy.

I have it for years with zero problems, I have a little suspicion but maybe wrong.

With friends training with i compare to some flat of course not climbing and I thing that a little less about 10-15 Watts than they are, but maybe my idea.

I use p2m with pc8 computer, what is the right protocol for my powermeter ?
At srm device agent I have these options
CTF
RCP
TAW
TAC

Which powermeters do your friends use? Single side?

10-15 watts compared to your friend is meaningless. The only way to check it against another meter is to ride both on the same bike at the same time. If you could find access to a smart trainer you could compare to that.

Renata is the best indeed.
However their custumer support told me that any good quality brand will also work.
