Pm1

[[old] travisshue]

Last night I rowed 30minutes at 178.1W according to the moniter. Changing the units said 7075m. The pace conversion for 178.1W is around 2:05 whereas the pace I actually rowed was 2:07.1. Any Ideas?

The watts are accurate on the pm1 but the conversion is not, so calculating the watts conversion to pace is more accurate.<br><br>I used the pm1 until two years ago and then got the pm2+.<br><br>The pm2+ is sooooooo much better.

So what your saying is that i need to build my own table by doing pieces at a wattage and then plotting the W vs. Pace? The chart on the website is just wrong right?

Travis,<br><br>I would either use the pm1, or get the pm2 and use that.

The Model B I use has a PM1. <br><br>Do I need to go by the wattage that it gives me(178.1W) or the meters it tells me (7075m) in determining my pace? Using the meters yields 7075m for 30min(2:07.1). Using the Wattage yields 7200m(2:05.0).<br><br>I just want a way to moniter my average pace, the moniter wont display average pace/500m so Im gonna have to use the average Wattage readout. Since this thing is called an "ergometer" and an erg is a unit of power, the power it says would have to be the correct reading.<br><br>I appreciate all your help John, you've answered all the goofy questions Ive posted on this board.

I considered that when I had the pm1 but stuck with the pace reading even though it was slower. <br><br>I don't know what the chart on the web site is.<br><br>The pm2+ has so many great functions, accurate conversion to pace, average splits, intermediate splits for any intermediate time and/or distance, projected pace (my favorite for time trials), and the regular time/meters function. Also with the pm2+ you have the connection for your computer use and also online racing or training.

I mailed paul about the chart, itll save me a lot of time. Last night I rowed a little piece at 252.2W. It was at the same pace that I should have had to pull a 280W to get. Problem is Im workin slower than the 1:55 agreement point between the pm1 and 2+. Pace prediction says 170.2W for a 2:07.2, but you actually have to pull 178W to get that pace. <br><br>Ive been using the C2B at work, Ill just get a C2D before too much longer and stop the confusion.<br><br>Paul can you elaborate on the "erg" comment. I have some of my own thoughts on the subject.

Travis,<br><br>The pm1 / pm2 chart shows differences but is not consistent because the pm1 is not consistent.<br><br>For example a pm1 watts reading equal to 2:05 might show a pace of 2:07.5 on one occasion and a 2:06.5 on another.<br><br>Thus converting the pm1 watts to pace would be most accurate and for that you would need to make your own chart.
