TPO Letter Sequence

Hello, I have attached a day/evening session TPO chart image. The letter sequence is as follows:

BCDEFGHIJKLMNOPQRSTUVWXabcdefghijklmnopqrstuvwxyzA

As expected, the day session (profile on left) begins with letter B and ends with P.

For the evening session, I'd like it to start with "Q", since it follows P. I'd rather it not start the letter sequence again. Is this possible?

First you will want to set this input to Yes:

The TPO Letter Sequence input can hold up to 256 characters.

When Letters Always Start at Primary Session Start Time, then the first letter is for the first subperiod (by default 30 minutes) starting at the Session Times >> Start Time in Chart Settings. The second letter is for the next adjacent subperiod timewise. For example, if the start time is 9:30, the second subperiod would start at 10:00 if using a 30 minute subperiod.

At 16:15, the 1-based index of the particular letter that you will want to set to Q is calculated as follows:
(Evening Session Start Time in Minutes - Start Time in Minutes) / Subperiod time in minutes + 1

This is the formula in this particular example:
(975- 570) / 10 + 1 = 41.5

You'll want around this up to 42. So you will want to change the 42nd letter to Q
