Slack in cord?

[PeterVNC]

Hi, I'm wrapping up my first season on the Skierg and playing around with sprinting for the first time. I have experienced slack in the cord lines of my Skierg at certain times recently. I can't figure out why or even what combinations of s/m, wattage, drag, or stroke mechanics bring this on but it seems that it has only happened relatively late in very intense efforts. Has anyone else experienced this? I'm wondering if it's something with my form breaking down. I can't believe that I'm raising my arms faster than the recoil of the cord but it feels like that is what is happening. Any ideas on what is happening and a remedy? It kills power on the strokes where this happens. Thanks for any advice.

Not a skierg pro, but some experience during 1 1/2 year gym usage.
Cord slack can happen on high rates, very likely worsens when technique breaks down. Watts and drag don't play a role in it, as these are purely linked to the active drive phase of the stroke, not the recovery, when slack can happen.
Out of interest, about what rate and pace are we talking about in these sprint pieces? When I do sprints like a 100m, I get the splits down to 1:22 at a rate of mid 60s and sometimes it feels like you describe, but mostly when I get out of balance due to the high rate (= technique drops off).
