Thank you all for the advice.
I accept that using FB paper for tests is right. However the ease of getting a good RC test print and then just adding a stop had an appeal to a lazy streak in me, so easy to dry and so forth, and much cheaper to work out burn and dodge times.
So my lesson today is dont be cheap and lazy it really is not worth it.
Also aperture adjustment are not always going to be linear, it makes a lot more sense to control time in f stops than the aperture.
Thanks everyone.
