Canalplan has it as 6.5 miles and 20 locks.

Google has it at 5.25 miles and 20 locks.

So one of them is wrong - but which one is it?

Or are they both wrong? CRT put it as

Length    5.8 miles
Locks    16

Looking around at other sites it's hard to tell because sometimes Delph locks and that part of the canal seem to be included as part of the canal and sometimes they're not.

Bradshaw has it as
3m2f and 20 locks to Lay's Junction
Thence 1m7f to the Dudley at Black Delph.

So 5m1f (5.125 miles)

The error seems to be between Black Delph and Leys Junction which I cruised in 40 minutes last week which is what drew my attention to the discrepancy. The Nicholson's guide shows it as approximately 2 miles which correlates well to 40 minutes cruising.

The relative distances between the bridges on that section look correct so perhaps they are just scaled wrongly because of an incorrect assumption on the overall length.

(Above post entered while I was typing confirms the issue).

Your guess is right - a largish distance is spread out using the relative spacing of bridges and other features.  

The internal distance table for the Stourbridge Main Line looks like this:
Stourton Junction   Wordsley Junction   2   2
Wordsley Junction   Leys Junction   1.3   3.3
Leys Junction   Black Delph   3.3   6.6

The first column of numbers is that section in miles, the second the cumulative total.  That's clearly wrong.

I've discovered that we lost the ability to edit distance tables during the major update to the gazetteer - I'll fix that and then fix this.
