That is spot on. I'm using some original Cheddar Models steam oil (the dark treacle coloured 460) and have settled on just under 1/8th of a turn open works best for my Samson.
Tag Gorton advised me to start with the control valve closed until you had cleared the cylinders of the condensate, open it for the run, close it during any water refills (I do this at least once during a run) then open it again, and at the end of a run fully close it again.

I was given a good tip for emptying centre flue boilers. Use your 50 mls syringe & tubing to suck as much water out of the boiler as possible. Pull the syringe's plunger fully out, insert the tubing as far as possible into the boiler, hold the loco upside down & depress the syringe's plunger. Repeat as necessary until no more water is ejected from the boiler.
It is rather tricky initially holding the loco upside down in one hand & pushing the plunger with the other hand, but you soon work out how to do it for each loco.
Watch out for the baffle plate in Samson's steam dome - there are only 2 holes through which you can insert the tubing.
