Default Short Course Meters Green Zone Set with Tempo

At my height of 72 inches, my Green Zone for a 25m pool runs from a smidge below 16 SPL (let's call it 15.75) to a smidge below 20 SPL - say 19.75 strokes.

Tonight, at the Eisenhower Park Aquatic Center on Long Island I had a 25m lane to myself for over an hour. I took advantage to continue my experiment with finding out what happens to my stroke count as I increase tempo in .01 sec. increments from 1.2 to 1.0 sec/stroke.

I started at 1.3 and used the first 5 x 100 (at 1.3, 1.28, 1.26, 1.24, 1.22) as a tuneup. My stroke count remained consistent at 16SPL or 64 strokes/100m.

I was able to hold that count to 1.18. I held at or under 68 strokes/17SPL to 1.07, and 72 strokes/18 SPL to 1.02. My last 2 x 100 were at 74 strokes (18.5 SPL).

So, using Tempo to learn a more precise sense of my personal Green Zone my range was 16 to 18.5 between 1.2 and 1.0.

As with the experiments I conducted in a 50M and 25y pool this set suggests that my best Tempo range for setting my Green Zone is 1.15 to 0.95 sec/stroke.

I have surgery Jan 25. I'll swim as regularly as possible until then. After surgery I'll 'go quiet' for about a month as swimming will be verboten.

While I'm recovering I invite others to try this test and post their data on this thread.
