I checked this sphere (it was difficult to get an accurate offset) and I came up with an approximate offset of .625 inches ( 15.875 mm ). This works out to a weight offset of 1.4 Kg at the worst condition. That condition would be with the water level at mid-sphere. The problem goes away at the Max and Min values. My judgement would be that this is not significant and within the bounce we should expected to see on the sensor due to motion. If we want to add this factor into the software and it is not troublesome issue I would also support that. We can always see how testing goes and determine it later unless that brings up an issue for Andy and his schdeule. If that is the case then we should go ahead and implement it now. Let me know if we need to get together and discuss this or if waiting is sufficient. - Bill -- ******************************************************** William J.
