The tests were done over a day, takes nearly an hour to empty the bottle, the amount left in the bottle is negligible
most certainly not the amount that we are looking for, the drip is just off center, prob about 5cm from the hole and
the bottle is sat in the cone, even if the amount lost due to error is 2 mm (of which theres no chance) it still
wouldnt equate to the amount missing, also the amount missing corresponds to the amount of difference between the
manual 4" and the bucket during rainfall, i know you are trying to find fault, but the test was done 4 times, albeit not
scientifically accurate but accurate with regards to to mount of water used, i have an accurate 60ml syringe marked in
1ml increments, so at i at least say that part is as good as i can get it, there is no way i am loosing 6-8mm during test
