Yep, from what I've seen the adjustment is usually near the far end (say the last quarter) of the adjustment slot.

Here's a picture of an '87 distibutor set to about 12 advance...which required machining the slot a little bit (without which, I could get only 8 degrees advance before running out of adjustment room).

Now for the disclaimer: To protect the innocent and to ward off any lawsuits for plagiarism, the following picture is not mine...but just happens to be exactly like mine. Thanks go to the anonymous donor.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
