Cracked the problem with the 15 second sample rate now, the equipment samples iniatially at 40 times per second, counts a 1000 samples, then drops to 20 x a second, another 1000 samples and halves again etc etc.
Amazing what you can find out when you read the instruction manual :lol:
If its not raining i will attempt the experiment one more time, this time resseting and recording each jet size on its own.
Recording sessions lasting less than 13 minutes, will give samples at 1.25 per second, and put to bed the doubts of the previous experiment
