Ratio

Display stroke ratio of recovery:drive time.

Not possible without considerable complication with the likes of a photo interupter of magnetic proximity switch or the like on the slide, even then its going to be a problem as your travel on the slide is not consistant. There are other options but they are just not practical and would be horribly expensive, with losses in friction for a varaible you don't need. I guess you could run a timer on the force curve and then look at where the flywheel begins to accelerate again in the drive to work out the recovery time, that would be easier but the accuracy would be a bit suspect.

Still waiting for something more usefull like the SPM down to 1/10ths for the whole row in the logcard results and this is very easy math in the monitor. Just run a counter put the result in a register and then divide the total by the total time and you have the average XX.X SPM for the row and display it in the top line of the logcard result. The longer the row the more accurate the result.

I guess C2 have to draw the line between what is vital and what is just "cool to have" on you monitor.

Actually, it is extremely easy to do - as long as you have a PC that is close enough to the C2 to attach via a USB lead, and can write some simple VBA routines in Microsoft Excel. When I say simple I mmean SIMPLE - I'm not a programmer, and I couuld manage it within minutes of installing Chris Brett's PMI interface.

It has beeen a year or two since I have used it, but I seem to remember that it has functions that allow capture of drive duration and total stroke duration - tus facilitating derivation of drive:recovery ratio. I used to log stroke-by-stroke data using the PMI interface with Excel. I could display and collect exactly the information that I was interested in. I also produced summary graphs of data from rows, and also analyses of paces for all strokes done at particular stroke rates, e.g. average 2:05.3 at 20spm, with a range of 2:03.7 to 2:07.1 (fictitiouus numbers).

If your capable of "Hello World", give it a try - it's great ffun.

Cheers,
Dave.

Display stroke ratio of recovery:drive time.

It has been done as a relatively easy calculation from the displayed force curve. I believe that it is also available from Ergmonitor.
