So I should basically forget about the mixture given the flight profile and leave it full rich (it's a UK airport so airfield elev is I presume irrelevant), and it's slow with the power reductions and speed increase.
Attached article was interesting. With a CS prop what MP reduction would be equivalent to the 150 / 100 rpm throttle reduction the author was recommending. Or is this the wrong way to look at the problem.
