7/8 day 70 hour clarification

I thought I understood log book rules, but have recently heard conflicting information on how to tally toward the 70.

Basically I'd like to know how many on-duty/driving hours you can average each day before hitting the 34 hour reset

Is it 7 days:
1) 9.9
2) 9.9
3) 9.9
4) 9.9
5) 9.9
6) 9.9
7) 9.9
-------
69.3 hours total (10.6 hours available on 8th day)


Or is it 8 days:
1) 8.7
2) 8.7
3) 8.7
4) 8.7
5) 8.7
6) 8.7
7) 8.7
8) 8.7
-------
69.6 hours total (9.1 hours available on 9th day)


Thanks,

Thanks. So (assuming you could get the loads) it would be best to just take a 34-hour reset at the conclusion of your 6th consecutive 11-hour day:
