Just a hunch, but using a 30 sec moving average of power, but a CURRENT value for HR, as it is effectively already a moving average, one implemented very efficiently by biology, will probably get an even higher r.
And then, I'd try t from 20 to 60 seconds in 1 second intervals to see which lag factor was most effective (at least for that individual).
(and I've been meaning to do this for a while, but the stupid data files are all proprietary formats rather than the nice old CSV files I used to get from my power tap, and I hate XML with an absolute passion)
