To me, when the directions say that, it isn't critical if you get the spacing off by one or two stitches.
So. I divide the number of stitches into halves: for 10 stitches, that would be 5 and 5.
Then I fold the work where I'm supposed to increase on in half and mark it with a safety pin or a piece of yarn. For 5 stitches, I'd again fold the first half of the piece in half and mark it.
So for this first half-of-a-half, I need to increase 2 sts between the edge and the 1st marker. Then increase 1 st at the marker itself. Then increase 2 more between the marker and your half-way marker.
Comes out pretty evenly - I've not had any real problems. This also works well when you have to pick up x number of stitches around a neckline or an armhole.
If they wanted anything more precise, they'd've put it into the directions, right? Right.

The Following User Says Thank You to DorothyDot For This Useful Post:
A pattern usually has several different sizes and you may need to increase different numbers of sts, so writing it to `inc X sts evenly spaced' is much easier. It's not too hard to figure out - if you're to inc 10sts even spaced and you have 60 sts, you inc every 6 sts.
I agree with DorothyDot that it is not that critical to get them just so. When you start out you really sweat all this stuff, but after you get a little experience you find it is not a life of death issue. :-) Get them as even as you can without having to stress out too much and you should probably be safe.
