with due respect: Saturn rotation 10 hrs, at 10 AU distance, 21 % of all the planetary mass.
Jupiter rotates at 10 hrs at ~ 5 AU distance 71 % of the total planetary mass;-- ergo: 92 %of all the planetary mass rotates at 10 hrs, in angular momentum terms also the Earth Moon system.
Respect aside, Jupiter rotates every 9.925 hours, Saturn at 10.6733. expressed using percent of mass rotation per hour using your numbers, we see that MOST planetary mass is rotating at 9.288143 hours, so still, no, most planetary mass doesn't rotate at 10 hours.
At least you've admitted you cherry pick things you don't understand to support your word salad numerology that even you can't explain.
