Yes Jack I meant splits not intervals! Thanks for the clarification!

So as a numerical explanation of my question:

Scenario A:
  • 1 x 30' split with 749 strokes - average spm of 24.97 is rounded down to 24
Scenario B:
  • 14 x 2' splits each with 51 strokes - so each split would have an spm of 25.5. rounded down to 25
  • 1 x 2' split of 49 strokes - so this split would have an spm of 24.5 and get rounded down to 24
  • Total number of strokes would be 763 (= 14 * 51 + 49, and 14 more than above)
  • Would the overall spm be based on these 763 strokes and come out at 25, or would it consider the 14 splits with 25 spm and the 1 split with 24 spm - average those to 24.93 ( = (14 * 25 + 24) / 15) and round down again to 24?
14 extra strokes! :shock:

Not that I'm planing to do this - I'm certainly not capable of that precision! Just keen to know. I will be aiming for a constant 24 when I do this. :D

Better job of demoing the ?, Rohan. I have no head for math puzzles but fools rush in . . . . I'm guessing the procedure in the PMs is an averaging of split averages as in your fourth bullet point and you get your 14 stroke free lunch. Doug Lawson the forum exspaminator (Citröen) is the expert on PM ops. You might want to get his take.

does the PM 5 allow for this level of SPM monitoring (not what blood is chatting about, just in general)?

It seems one would need to just set it at 24spm and hold steady, going above or below would blow the average and you wouldn't know where you're at in the end...?

PMs including 5 don't count strokes or perhaps better to say they provide no stroke total per split or overall on the results page. They do register time elapsed between one acceleration pulse from the flywheel and the pulse following, divide that time into 1' for a projected s/m which is then updated on each succeeding pulse. Or course the PM is recording the number of and results of the iterations of its rate projection operation as determinant of the rate average for each split.

After seeing Rohan's scenarios, I wonder if the Indy team also has in mind gaming the rate restriction.

Ouch.

Or I may not.

Henry suggested 10k + 1 or 2, or 30r20 - 2. Could well be new enough to this erging game that I'm enjoying newbie gains, or something about my height or sub optimal spm in other pieces, but this was 10k - 2, and at least - 4 (maybe even - 5) to my best 30r20. The last 6 minutes REALLY sucked.

HR spent 19:47 >= 180 and 8:29 >= 190, max 194. :shock:

That's klckin' it, Rohan!

I'm working my way up to 6800m. In a psychological gravity well at 2:16-2:20. Thinking maybe rowing to a watts goal (150-60) will get me out of this groove. I can handle 2:11 pace to just shy of 5k right now, 1" faster than 5k PB, so think I might make it in a month.

you might have noticed a very nice lwt 7807 - Chris is back! (and Anthony is his twin brother)
He is a gym buddy - quite good young triathlete coming back from injury who doesn't mind a challenge or 2 for cross training.

Wanted to do the ctc to get it over with. Will stay warm this week, and next weekend we will be off for a week to Barcelona. So not handy to do it after.

Hayfever, our house is surrounded by gras and flowers, now fully in bloom. Yesterday, it hit me hard, sneezed my lungs out and my eyes leaked water, no kidding :roll:
We cycled around a bit, grear weather, but very uncomfy. Have no medicine home, need to get asp monday. Don,t use medicine often, but this is needed now.

Erg today. Short wu, was already 24c, so knew it would be a slog, training is not aimed st this, warm, the hayfever. But ok.. ;-)

30 min, rate24, dr 125, strapped.

8288 148.5/24

145.9/48.8/49.9/50.4/48.0

It was pretty horrible, hurted a lot, but kept going to get it over with, pretty modest outcome, but was a max effort. At forhand I thought 8400 was doable, but not in current conditions.

Cd 10 min 2.54 yes that slow.

Henry that is still a very impressive outcome under what sounds like far from ideal conditions! Great stuff.

As noted in my post I can empathise about this being quite sucky. Hope the hay fever has cleared up a bit!

Relative maybe, but no, not good :D I am not in the camp of easy compliments, effort was there, no complains, but outcome mediocre :wink:

Bit better, but still there, thx.

I can remember the few here who have done >8300min in 30'. I don't think of them as mediocre. You'll be back to 8500 next time, Henry.

There won,t be a next time Jack. The Ctc stuff does not suit my training much these days. So this one attempt has to do. All in life is relative.
