The first number is the width measured sidewall to sidewall and is
stated as the section width. This measurement is based on a standard rim
width as stated by the tire manufacturer. A 205 width's recommended rim
width range is usually 5.5 to 7.0. Yes it will vary slightly depending
on the width of rim you mount it on.
Tread widths will vary from tire to tire depending on type of tire,
aspect ratio as well as manufacturer.

Not sure I agree with this Chris. The width across the points you
describe will vary depending on various other factors, e.g. width of
rim it is fitted to ( I know there are recommended rims for any given
width of tyre, but the recommendatuion is usually a range of rim
sizes); pressure the tyre is run at and weight of vehicle.
The actual tread width is a fixed amount for any tyre size, and seems
to me to be more accurate.
Still, I'm being pedantic I guess!
I agree your version of the profile % calculation.
What we need is someone running a 205 tyre to go and measure it!
