Counting Daily Running Increases

Tom tracks his running distances over a week, from Monday to Sunday. Your task is to determine the number of days on which his running distance increased compared to the previous day. Note that the comparison starts from Tuesday since Monday does not have a preceding day.

For example, given the distances [3, 4, 2, 5, 6, 3, 7], the result is 4 because the distance increased on 4 days.
