I am guessing your question is why is 100 watts (say 50 N and 2 m/s) which is clearly towards the middle of quadrant 4 not active recovery? My educated guess would be 2 m/s (~110 rpm) can not be active recovery due to the large amount of velocity leading to premature fatigue due to the fact it is way past the dividing line for the quadrants. I would assume that anything to the right of the 1.42 m/s pedal velocity line would lead to premature fatigue from excessive velocity and anything above the 211 N line would lead to premature fatigue due to excessive pedal force (for this specific example). This is my understanding of the benefits of quadrant analysis. To see the balance of your personal force and velocity ratios. Also this graph is solely based on the individual. Mine will look different from yours which will look different than this example. If I understand right that would make this descriptive.
If you still feel quadrant 4 could be active recovery would you agree that 100 m/s and 1 N is active recovery? It is still 100 watts which falls into active recovery.
Rereading the thread I see that I did oversimplify the boundaries way to much originally. Hopefully this post clarified. If I misunderstood what you were saying please let me know.
the answer may be in here somewhere--but I'm too lazy to read 67 pages of PT questions/answers. sorry.
My head unit is not reading the PT hub (no sensor indicator, no readings). While I was on the rollers the other day it was giving me some strange watts, I stopped and zero'ed the torque and then it couldn't find the hub anymore. Just like that...
I changed the bats two weeks ago (head unit and hub) the connectors are fine and in good contact, it still reads cadence fine. I didn't see any problem with the wire or sensor on the seat stays.
Am I missing something? Any suggestions?
gravity: it's not just a good idea, it's the law.
I loaded the trial of 3.0 and played with it for an hour or so. Not impressed.
I just ordered the Powertap Comp and as I wait, I have a few questions:
1. Can someone explain what the "Interval" display is? When I do my 20 minute Threshold test, is this the function I use or is there a regular "time" display?
2. Ideally, I will want power, speed and cadence all on the same screen. Can I then toggle to get the other stats (time, distance, time of day..etc)? Thanks
thanks. So WKO+ allows you to take that 20 minute portion and get an average? Because the whole ride would include warmup/cooldown, but I really want the average power from that 20 minute portion, correct?
You can set cadence as your "big" number instead of speed, otherwise you won't be able to see time and cadence at the same time. I find time to be one of the more important data during intervals (especially < 20' intervals). You don't need time of day during an interval
dhale50: I'd recommend you read through the (downloadable) instructions for the head unit and see how intervals work. They're actually really handy. "Interval mode" is what brian416 mentioned, and it always displays information for the current interval (only). So, speed, distance, time, averages, everything is for the current interval. If you hit both buttons at the same time, it starts a new interval. So, for an interval workout, I hold left for 2s, starts interval mode and my first interval. When I finish, I tap both buttons, and "interval 2" will be my recovery interval. Interval 3 will be my next work interval, and so on.
There's also an interval browse mode, where you can change which interval is being displayed (current or past intervals). This is really useful when I'm trying to push negative splits on hill repeats, or during the STUCI intervals, where the pace for the previous interval determines the target for the next one.

Or, just do the test and WKO allows me to take that 20 minute portion and get the average?
I like intervals because I've got a time display for that specific effort. For a 20' test, I would just ride there out of interval mode, hold "Mode" for 2", and start going hard just as the display shows the interval. Now I can glance down and see how much time has gone by. Also, if I look at avg W, I can see how I'm doing against my expected result.
I personally do not use the interval mode on my powertap. one of the other main screens will display max average power for :30, 1:00, 5:00 and 20:00. also like stated wko will automatically tell you your max power for all different times. the interval function may be beneficial if you want to compare a bunch of say 10 minute efforts. The intervals will allow you to easily get the data for each but really you can just look at the ride and highlight the sections manually.
For workouts like Friel's pace intervals (My training partners and I call them STUCI intervals -- same time until can't improve), you have to use interval mode to know the exact average of your last interval.
Jynx is right though, for less structured workouts, it's not important. It sure is convenient though.
