Yes I was referring to the reduction in g due to the curved path at speed, the classic in a lift with no windows experiment.
You are wrong about deep oceanic tides. they are pretty much non existent in the middle of the oceans and build up around continental masses.
My point is that your earlier explanation
"The tidal acceleration moves water about two meters in six hours. The free fall acceleration moves water two meters in about 0.4 seconds. The force is related to the square of the ratio of those times. That's gives a measure of the low-down scale of tidal forces"
was codswallop. It is vastly more complex. I thought of a few more factors including coriolis effect, centripetal effects etc.
To characterise it as (and I am paraphrasing you here)
"tides go up and down with very little acceleration compared to water falling in free fall therefore tidal effects are negligible"
is just wrong.
