[Touch Diamond, MDA Compact IV General] logger:
OK thanks. Was actually after the MINIMUM time between polls not the max but I think I found it today in any case. With sample time set to 250ms or 4 per second you can see the app only wrote three records per second instead of the expected four. So I am surmising that the minimum time is 1/3 of a sec or 333ms.

What I do find particularlay interesting is how rapidly the accelerations can change. At TD point in a 1 sec period the vert G goes from 1.12 to 1.7 and down to 0.61 again. Which shows that if you have sample period of 1sec or more you can easily miss a G spike. This is explains why a person can feel a big bang on TD but a older G reader with 1 sec sampling misses it and appear to under read. Amazing that a $600 phone has better resolution that a $60mill aeroplane.
