Peewee, the short answer is: no, I didn't. But I suppose you'd rather have the long answer.
Let's keep it simple, Peewee. If a radius in any drawing is stated as, for example R20, then it means 20 mm, not some percentage of anything.
Moreover, the RSW drawings that you refer to, were the drawings that I could release at that time; they were
not the RSA drawings.
Things have become even simpler since then: in the RSA cylinder the inner walls of the A-ports have one constant radius of 22,6 mm. If you wish to convert that to a percentage of the 54,5 mm RSA
stroke (not the bore), be my guest.
There
are some radii that I have quoted as being a certain percentage. They are the radius at the top edge of the main exhaust port (6% of the stroke) and the radius at the top edge of a radiused piston (8% of the stroke). But you cannot use these values just like that because they are not simply tangential at both ends, as you can see in the picture of the radiused piston below.
