Just got PT and downloaded WKO and need some help with readings from the PT.
Below is one lap from Saturday. (Club ride, traffic lights etc)

Can somebody please translate all this so I know what the heck I'm looking at?

Probably should have read it before investing in the PT, but no use crying over spilled milk.

Here's a Powertap question: if you get your head unit to 'learn' the ID of a fork sensor or hub, can you then teach it to learn a second fork sensor or hub and will it retain that in its memory? I think the answer is 'yes' because I already have my Ptap head unit recognizing a separate hub and fork sensor, I don't see why it wouldn't retain a third ID once it has recognized it and stored it in memory.

Also, has anyone had any experience with that new fancier Joule head unit Saris has been selling this year? Looks pretty cool. Easy enough to deploy, it's Ant+, you just whack it up on your bike, ID it to the hub and off you go.

Not enough info.

How much do you weigh?

How hard did the ride feel?

Your FTP could be set too low unless it was pretty hard, but with an average HR of 149 it doesn't seem too tough. Just a guess.

And yeah the book BD posted, and/or read all this. All of it.

Jancouver

Thanks for the link. I will read it all

To answer your questions:
195lb
How hard? Well, typical club ride, start easy, then the pace will pick up, then it will be interrupted by some traffic lights. Then there will be a section where we will go fairly hard, regroup, easy to moderate to the final few miles where we go hard.

I guess my FTP was set by default at 160 which is probably too low. My HR max is in high 180s.

kudude

your ftp is > 160 W. guaranteed

Also, just ride around with the ptap for awhile and get a feel for what various efforts feel like.

goal number 1: crack 4 digits on the max

Psimet2001 

Yeah...your ftp <> 160. closer to 300. BTW -I hate you.

Jancouver

I know you do and trust me, the only reason I went with my LBS, is that they were able to build the wheelset right away since they had the rims/hub on hand.
But no worries, I will be buying some more wheels soon and you will get my business!

Keep in mind that when you stop at a traffic light, you will get time to recover, but that time will not be reflected in average or normalized power [hence inflating your numbers somewhat]

Jancouver

Really? Even though the auto pause function is turned off?

johnybutts

auto-pause is off, 0s are averaged.

If that's only one of the laps, your FTP is set WAY too low. It would be closer to 330-340ish, I'd say. 90 min @ 302, at full effort would normally be ~95% FTP. Assuming it wasn't an all out effort (as it was only 1 of the laps), it was at best 85-90%, which would still be a pretty stiff intensity.

Other than that, there's nothing else to be said about raw numbers.

Psimet2001 

Haha...no worries. I "hate" you because of your power. We aren't that far apart weight wise and your power is impressive compared to me........but then again....

I have "the book" if you want to borrow it. Also, did you set your Garmin to record data every second instead of leaving it on "smart recording"?

Urthwhyte

Garmin units automatically switch to "Every Second" when they detect a power meter

bdcheung

are you sure about that? Mine didn't with my SRM. Neither did my friend's, with his PowerTap.

Urthwhyte

I'm 99% certain that it's true for the 310XT, and thought that Garmin had patched the 705 to default to it as well, because with smart recording FTP and average power come out as highly inaccurate. Unsure of the 500s status

Jancouver

I just ordered the book last night. Thanks for the offer! I will have to check my Garmin (705) for those data recording settings.

Jancouver

I'm really not sure where my power is compare to others but since I'm still getting dropped on some of the local rides I know that I need to improve my power and specially my W/Kg and thats why I bought the PT

kepst

This is truth for the 500.

bdcheung

My comments were made with regard to the Edge 705, so we may be talking about apples and oranges here.

mattm

Yeah I don't think my 705 did the auto-switch to 1-sec recording.

efficiency

When the Garmin 705 first came out, this was not true, and lots of people had questions about their strange looking ride files.

Urthwhyte

The 705 bug was fixed in a later firmware, but it was intended to switch automatically

bdcheung

doesn't hurt to double-check, no matter which Garmin you own.
