I set my Repeat condition to limit the repetitions to the page count of a document which had 6 pages but found that the repeat loop only ran 5 times.

When I checked the workflow history it is says that the iteration limit has been reached, not the number of repetitions. So it is an iteration limit, not a repetition limit.

The number of repetitions is not equal to the iteration if you start with 1.

For example if I wanted to limit the number of repetitions to 1, then the repeat loop would never run because 1 is the first iteration. But logically if I say I want no more than 1 repetition, it should be able to run once no matter what the iteration is.

So it should probably say something like halt on iteration # instead.
