One thing I forgot. Both the Hebrew and Gregorian calendars have leap years to correct for extra days, and drifting years. I think this concept can be applied to the suggested pattern of Jubilees and Shmitas in my other post just a second ago. Since Jubilee years are in increments of 50, and Shmitas are in increments of 7...leading up to 49, there will always be an extra years difference. But applying the model of every Jubilee, also being that 1st year of the 7...49 year cycle, eliminates any "drifting"...which is exactly what leap years do. So its like were adding the leap year principle to the counting of shmita's and Jubilees. And when we do this...the numbers work, and all pieces of the puzzle fit.
