I apologize for causing you any inconvenience. And took up your time.

I'll try to explain again. In details
for convenience, I gave an example of a start at 00:00, and not at 00:05 as in the example above. Sorry again.

Session Start (6 hours):
(line 0) Time 06:00 - Sub-Session B -- + 60 min = 07:00 (120 minutes until next event)
(line 1) Time 07:00 - Sub-Session B - + 60 min = 08:00 (60 minutes until next event)
(line 2) Time 08:00 - Sub-Session А -- Event for 4 minutes. 08:00 + 4 min = 08:04 (56 minutes until next event)
(line 3) Time 09:00 - Sub-Session А -- Event for 4 minutes. 09:00 + 4 min = 09:04 (56 minutes until next event)
(line 4) Time 10:00 - Sub-Session А -- Event for 4 minutes. 10:00 + 4 min = 10:04 (176 minutes until next event)
Session End:
Repeat (6 hours):
(line 0) Time 11:00 - Sub-Session B -- + 60 min = 12:00 (120 minutes until next event)
(line 1) Time 12:00 - Sub-Session B - + 60 min = 13:00 (60 minutes until next event)
(line 2) Time 13:00 - Sub-Session А -- Event for 4 minutes. 13:00 + 4 min = 13:04 (56 minutes until next event)
(line 3) Time 14:00 - Sub-Session А -- Event for 4 minutes. 14:00 + 4 min = 14:04 (56 minutes until next event)
(line 4) Time 15:00 - Sub-Session А -- Event for 4 minutes. 15:00 + 4 min = 15:04 (176 minutes until next event)


It seems like we just can't understand each other. I'll try to explain everything. (line 0 and 1 will be both "false") (line 2,3 and 4 will be like "true")
If we fail to understand each other, I will have to abandon this idea =(
