no...I requested that it be written every 100 ms (stored the number 10 in the joyres.txt file). I even deleted the joyres.txt file and looked at the result - the program stops writing to the data file after 32760 ms. So it appears to be some kind of upper limit imposed by DirectRT, or perhaps by the format of the txt file. The problem is that I need a large time series for the kind of analysis I need to do, otherwise I would just use Medialab's online ratings measure.
