I would like help trying to create a formula to subtract the difference in time between the first blow and the last blow of the same sequence. So between Lobtailing and Lobtailing and between Lobtailing and Fluke Up Dive. So getting the difference between 21:33.6 - 22:36.3 and 24:07.6 - 24:29.8. Any ideas?

Thanks.

Hi,

Don't know how you might want your layout to look like, but here's one way, shown with or without the words "Time interval is:", which you can change to say anything you want.

3Blow21:33.621:33.6
4Blow22:21.7
5Blow22:36.3Time interval is: 01.02.7
6Lobtailing23:26.5
7Lobtailing23:30.6
8Blow24:07.624:07.6
9Blow24:29.8Time interval is: 00.22.2
10Fluke Up Dive24:50.9

And here's a solution using a helper column (in column C).

I'm assuming all cell references are the same as in post #4 .

The helper column can be hidden if required.

In C2
=IF(AND(A2="Blow",A1<>"Blow"),B2,IF(AND(A2="Blow",A1="Blow"),C1,0))

In D2
=IF(AND(A2="Blow",A3<>"Blow"),B2-C2,"")

And copy both down as far as required.
