Earth core rotation -hypothesis contd

 If you calculate with exact time,and consider the time when Jupiter attains same spot...it is like this..

Exact time of rotation are
Jupiter 11.86 Yrs
Saturn  29.46 yrs

Assuming When Jupiter occupy the the same soot and Saturn opposes Jupiter it happens only after Jupiter's 6th round
11.86 x6 =71.16 yrs

And after 71.16 yrs Saturn have completed  71.16 ÷29.46=2.415 round
So Saturn is opposing Jupiter ,who has occupied the same location After 6th round
In accuracy is 2.5-2.415 = 0.085 of circle
Ie 0.085x 29.46 =2.5 years

So after every 71 16 years ,the core remains standstill for about 2.5 years ,and then change the direction .
