Stroke, stroke, stroke,...

Usually when I swim a 500 SCY, the Speedo usually reports 200 to 210
cycles (400 to 420 strokes), although I got 180 once.  For the 1000
SCY, I usually get 400 to 410 cycles (800 to 820 strokes), although I
got 350 once.  That's about 20 or 21 strokes per length.  I haven't
been happy with these numbers, but I have been getting steadily faster
and I just assumed I was a bit inefficient over distance.

I left my Stroke Monitor in the locker today, so I just started
swimming and counting strokes. I was surprised.  First length - 14,
second length - 15, then 16s, 17s & some 18s.  If I averaged 17, I did
500 in 340 strokes or 170 cycles.

When I sprint, the Speedo usually reports 19 or 20 cycles (38 to 40
strokes) in the 50 SCY.  Today I counted 35 in a sprint.  For my next
workout, I'll have to count carefully and compare with the Speedo.

While I'm pleased that I'm getting better stroke length, I'm wondering
where the Speedo could be finding the extra cycles.  The only thing
that occurs to me is that my arm might be going in and out of the water
on the reach.  Anyone else notice this?

Hi Donal:

The stroke monitor counts a stroke when it --enters-- the water, not exits.
In other words, it counts  the number of times your hand (wearing the
monitor) hits the water. Whether or not you complete a stroke is not
factored.

This sometimes throws people off who might not count *half* strokes that
occasionally occur during turns and when you finish.

Another item to be aware of is the hand you wear it on. For example, I wear
mine on my left hand. Typically, the first stroke I take off the walls is
with my right hand. However, every now and then, I'll breakout taking a
stroke with my left hand. The monitor catches it every time.

It could be that when you are counting yourself, you are more conscious of
the number of strokes you take.  Therefore you think about taking fewer
strokes.  When you let the stroke monitor do the counting for you, are you
really thinking about stroke count?  Probably not.

I could see that accounting for an extra stroke per length, but not the
difference between 17/18 and 20/21.

That would explain why my stroke count went up when I started swimming
alternate lengths breathing to the left.

I thought about this too, but as a TI alum, I almost always think
about stroke count.  Also, in the 50 sprint, I was pulling hard.

Today:
Dist  Cycles->Strokes
200       78->156      78 Counted hits
200       75->150     144 Counted strokes
100       39-> 78      71 Counted strokes
50 (36")  18-> 36      32 Counted strokes
50 (45")  17-> 34      35 Counted strokes

When I swim slow, deliberate TI-style, the SM is dead-on.  When
I swim faster, I must add in half-strokes at the turns.  I also
caught my left wrist very close to the surface during one flip
turn.
