Doesn't TP already do that badly enough?

It's projected.
TP looks for 20min efforts you've actually done.
WKO4 looks at your entire curve and projects a 20min best possible value.

It's all far more info than I need.

Yeah - I'd prefer to use actual benchmarks than predicting things from rides. You learn more from doing something like a 20min test (eg. pacing, RPE) so it's quite a handy thing to plan in.

what did you do on your rollers session out of interest?

The session was 30s flat out sprint intervals; 150-160rpm... With a warm up and cool down. Pretty unpleasant to do at 7am, especially after racing in the wet last night.

Yeah, for sure.

In related news, WKO crashed when trying to open a graph, now when I try open it, it just bounces in the tray and comes up as not responding.

Re power spikes.

I had a biggie on my last ride. Z5 intervals. Using a garmin 920 XT watch.

Set off for my second interval. Glance down to check I'm not going off too hard. Current av power = 350w, lap av power = 950w and dropping. The slow rate the lap average power was dropping made me think it was either a very high, or very long (1second maybe) spike. This was backed up from my TSS jumping from 70 to 258.

Figured I'd have to fix that or my PMC would be trashed.

Uploaded to TP.
No spike, TSS of 98.

This makes me suspect my garmin of having a brain fart. Kinda annoying as I enjoy laughing at Edge users.

TP has an algorithm to filter out data spikes. Look in the file and see it'll be there.

Ah. Did wonder about that.

Another reason for me just to stick to TP.

Sometimes garmins are dicks too. Mine occasionally shows incorrect stuff, only for the data to appear as it should in TP and strava.

P2M want my p2m back to look at re data spikes.

@dan can you drop the tool back when possible.

Interesting.

As I have no intention of using anything more in depth than TP. I guess it doesn't matter.

Unless it's a increasing thing.

I suspect I just wasn't aware of it until now.

Dunno, depends how many you get. A few, okay. Lots, not okay. I get a fair few.

To me I question te accuracy of a device that gives me erroneous readings. They can have it back to look at.

Other than 'time in power zones' and 'peak xxmins' etc does TP offer any graphs for analysis of power, perhaps that I'm missing?

There is a scatter graph with various axis option, but I don't seem to be able to set it up for quadrant analysis or anything that feels useful.

You can't do QA.

You used to be able to on classic TP.

Yeah sure - mine arrived yesterday. Will run it up to you today or first thing tomorrow.

No. It's actually pretty shit for analysis. I keel meaning to cancel my subscription - my coach doesn't like it either.

I can do this (see bottom image). Which is data from a (30s@125 / 30s@85%ftp) x 20 (but with warm-up data in their too).

It puts the average cadence at 85rpm (highlighted red by TP is the highest power figure for 85rpm – for some reason). If I draw a line left from that to the centre(?) I can bodge my own version of this (below), an example (from Coggan's blog).

I guess it's deliberately basic to help sell WKO?

Yes. As you used to be able to do QA in training peaks classic. They then forced you onto new tp and removed classic just as wko4 came out.

Basically they're bell ends.

When convenient, won't send it off till Tuesday.

Yeah this...

What am I supposed to learn from the QA plot? I sometimes look at it (GC), but I'm not sure what it's trying tot tell me

It shows the neuromuscular demands.
