Greetings all. It's been a while since I've posted.

I have a column of data that contains numbers between 0 and 5. I currently found a formula that will provide me with the max number of consecutive appearances of the number 5. See below:
=MAX(FREQUENCY(IF('Utilisation Sheet'!AE10:AE57=5,ROW('Utilisation Sheet'!AE10:AE57)),IF('Utilisation Sheet'!AE10:AE57<>5,ROW('Utilisation Sheet'!AE10:AE57))))
Confirm with CSE.
I am looking to change this code subtly, so that it includes consecutive occurrences of 4 OR 5. e.g.

3
4
4
5
4
3
3
4
5
3

Would return 4, since I have 2 4's, a 5 and then another 4 and it is the highest run of this in the column. Can anyone help? All advice is much appreciated.
