During today's swim I felt fast and the data shows that I was moderately fast (for me). That's good. I'll accept that occasional good performance doesn't always show the true trend but this afternoon I'm prepared to consider that it does. It's also possible that the absence of a run yesterday might mean that I'm better recovered than sometimes.
I started with the intention not to be feeble in the warm up 200m and so I just did the lengths with no gaps. I didn't make a great effort to be fast but tried to apply myself. That resulted in sub 3minute/100m for 200m (with the sinky-legs). I've manage that in the SwimSmooth time trial but not otherwise. That good start had a good effect on my whole swim average. Then on the usual-effort alternated with 90%-effort lengths I focussed on some effort even when resting and then being faster with good 'feel for the water' whilst working harder.
This approach worked as I managed a number of lengths at 2:05min/100m or better and good averages throughout. Of course I tired towards the end of the session until the final pairs of lengths showed little difference between normal and hard as they were all becoming hard! My first set showed around 22strokes/33m but by the end it had risen to 26strokes/33m. Clearly I was losing hold and merely swinging my arms.
