Perhaps the simple solution to the dilema of choosing between overwriting of
previous data versus simply ceasing loging is to add a third option, which I
will call "data reduction".
If you get to the end of logger memory, then set a flag which says "data
reduction mode ON", and start overwriting every SECOND sample point. That
way, you end up with up to twice the time span logged, and probably don't
lose out on too much time resolution. If, during periods where the logger
is running at the faster rate e.g. near turnpoints, perhaps the algorithm
could be set up to detect the inter-sample period has been reduced (by
checking the stored data), and simply skipping over it somehow.
As a maker of such instruments i.e. the Joey, do you think it's (a)
feasible, and (b) at all a worthwhile logging option ?
Just curious - it's my engineering streak coming out in me !!!

For most people, the cost of the crimpers for the plastic telephone type of
connectors (which I presume are RJ-12 or RJ-45 or similar) probably costs
far more (up to $100 if I remember correctly) than carrying a few spare
cables.
