Well, the corollary to that is, "if you argue incorrectly, you're never right.”

Unless engine rpms were reduced down to about 71 during the run from noon to the corner as I posted in #28 above, the distance
traveled through the water over a given time period, which is what the log shows, should have been about the same as that over previous time periods of the same duration with the ship carrying the same revolutions. And the ship was making better than 22 knots through the water since noontime Saturday carrying an average of 75 rpms.
Or perhaps if you keep repeating the same old nonsense often enough it'll become fact?

You have obviously never used a Patent Log Sam., otherwise you would not have put your name to that nonsense. I know you have heard of set and drift, so perhaps you had a memory block?
We are waffling on about Patent Logs and things nautical. This is disrespectful to those members who find it hard to keep up. Perhaps if I explain in terms they can relate to, we can sort this out? Consider the following. I'm sure everyone can relate to this. First let me point out, that the rotator of a Walker Patent Log, performed in exactly the same way as does the turbine in the water- flow meter of a domestic water system, In the Walker Log, 9000 revolutions of the rotator = 1 nautical mile.
Like the rotator on the Log, the Turbine flow-meter (better described as an axial turbine) translates the mechanical action of the turbine rotating in the liquid flow around an axis into a user-readable rate of flow.
The turbine wheel is set in the path of a fluid stream. The flowing fluid impinges on the turbine blades, imparting a force to the blade surface and setting the rotor in motion. When a steady rotation speed has been reached, the speed is proportional to fluid velocity.Knowing this, apply it to the following hypothetical situation
A Turbine flow meter is installed. It measures tons of sea water passing through it per hour. 9000 revolutions of the turbine is equal to one tonne of flow.
At Noon, the Register shows 000.00 Tons and the Revolution Counter also indicates zero.
At 5-50 pm, the Revolution Counter shows 1131.3.K. However, the tonnage counter has failed.
Question 1: How many tonnes passed through the turbine during the period Noon to 6 pm?
Question 2: If there had been an error in the Revolution Counter and it was reading 11.7 K too low ( i.e more water than indicated had flowing through the turbine), what was the true value of delivery by 6 pm that evening?
