we do understand e.g.
00:00
01:15
02:30
03:45
05:00
06:15
07:30
08:45
10:00
11:15
12:30
13:45
15:00
16:15
17:30
18:45
20:00
21:15
22:30
23:45
Next day: 01:00
…
in general crons are not made for intervals
The strategy to split it into multiple crons will not work as 24*60 = 14440 / 75 = 19,2
As we do see there will be each day a new offset for the first start
when having a flexibility then change the inverval that it fits or omit one segment for syncing e.g. omit 23:45 loose 15 mins and get sync again on 00:00. now you can split the series into diferent crons
