I believe this is the right techdoc for your cassette:

The Sheldon tables imply that cassettes have uniform spacing, but as you're finding out, Shimano and others were willing to make things slightly uneven for better shifting. My 7-speed cassettes exhibit the same thing -- slightly wider spacing as you get to the small end of the cassette. Shimano hoped that by riveting a bunch of it together and making the remaining cogs and spacers unique, there would be less chance of spoiling this arrangement.
