(answered) IRQ priority explanation needed.

In my tusl2-c manual, I can see, the priority of the different IRQ channels. But I do not know, if:

A) Priority 1 is best (because, it is the 1st)
B) Priority 15 is the best (because, it is the Highest)

Wich one is true? A or B?

it is more complicated because the irqs go in a funny order.

0 1 (2) 8 9 10 11 12 13 14 15 3 4 5 6 7

8-15 were added later and go through 2 (very simplistic but good enough explanation i think)

0 is highest priority(best) and 7 is lowest

Further to this, what is the 'suggested' IRQ for a Luna/Pulsar (single card)? At the moment I have a Luna II in an ASUS CUSL2-C, slot 3, irq 5 (not shared via BIOS setting). Would the optimal setting be either 9 or 10 perhaps?
