PM5 Storing detailed data

Post by NdyGen » September 24th, 2015, 9:39 am

Could the pm5 please store some detailed data for each stroke during a workout and save this on the usb stick.

To save space on the stick only last 5 workouts would be an option. Older files could be cleaned to save space if needed.

The concept 2 utility could then export this data to csv and/ or a dataformat we could upload to various fitness sites (eg runkeeper, garmin connect etc)

To get those extra data you'll need to get RowPro. It's not going to happen with the small microcontroller in the PM5.

Even a small microcontroler should be able to store stroke data at that rate to a usbstick. No fancy calculations needed.

Just store the data and the utility will export to something that we can handle with Excel or a site.

Rowpro is nice but the pm5 surely should be able to do this. This feature would be great for a gym. Taking a laptop with rowpro is way more dificult than just a small usb stick.

Been asking for more data and more accurate data for ages out of the PM3/4 and PM5.

The ARM processor in the PM5 is able to EAT this for breakfast, even the older Atmel processor could have done what I needed but its doesn't get implemented and I have no idea why, but there are two options.

A. I'm the only one in the whole world who wants it.

B. Fixing it is an admission its been wrong for over 10 years

The average SPM in the results is totally worthless and still has not been fixed and this is so easy to rectify.

I have RowPro and that still doesn't give me everything I need, its better it that it actually gives you live pace on screen PER STROKE to 1/10th of a second. The problem with the PM is too much rounding so when you really try to analyse your performance based on the PM data alone you cannot do it.

Concept 2 simply need to add a stroke counter into the firmware and do a simple calc at the end using the time. Not sure why you would need to record individual data on every stroke, my push is just for a total number of strokes ! info on every stroke, that's probably going too far, what you need is accurate pace and time information which are there already just the average spm for the entire row needs fixing. I have never looked too closely at the heartrate information, that's probably not being sampled often enough to get a decent average either but it can vary so much from day to day doing the identical workout its much harder to quantify if you trying to track performance gains in the short term.

I guess you're not alone anymore :wink:

The ARM in the Pm5 is powerfull enough to satisfy RowPro's needs so puttings the same data into a file seems peanuts to me.

Come on concept, free us from sticking laptops and/or Ergstick like solutions to our PM's just to get data that's already in there.

I'd guess the problem Concept2 are addressing is backwards compatibility with the PM4 and PM3. That's one of the reasons the maths never changed from the broken way a PM2/PM2+ rounded the data.

In case you are not aware, C2 solved this when they launched the new log and ErgData app on iOS or Android earlier this year. It will send per stroke data to the log and you can download a csv from the site for each workout.

Looks something like this:
"Stroke Number","Time (seconds)","Distance (meters)","Pace (seconds per 500m","Stroke Rate","Heart Rate"
"1","3.1","9.4","180.3","0","67"
"2","5.6","18.7","139.2","25","67"
"3","7.7","26.4","139.2","25","68"
"4","10.3","36.2","132.6","25","72"
"5","12.3","43.9","132.6","25","73"
...
