Counting between major steps in data

[David Cuthill]

I have a column of data that I want to step through and count how many values there are between each major value. So from value 18.00 to 17.75 there are 4 values; from 17.75 to the next 17.75 there are 3 values. I then want to summarize the outcome in a column as ...

4
3
2
4
....


The major and minor values can vary.

I'm sure how to attack this problem and would appreciate some guidance.

thanks
