Second one up, this is actually really fun
EDIT - I've just calculated the length of what the track would be for Modulo(7)
So there are 6 individual Pisano periods mod(7) of lengths (in bars/beats) - 4/3, 5/2, 6, 6/1, 6/3, and 7/2 in 4/4 time.
Converted to base(10) these lengths equal
19, 22, 24, 25, 27, and 30 respectively.
The lowest common multiple of these six numbers is
1,128,600.
So
1,128,600 beats @ 100bpm equals (you guessed it!) 188.1hours.
That's 188.1 hours of unique time patterns consisting of the 6 tracks before the loops catch up with each other and repeat.
SECOND EDIT - recalculated
