Stats can be pushed higher than shown on the bonus spells table if a character reaches high enough mythic tier and has other bonuses, such as inherent, age etc.
Without giving your opinion on how you think it should work, by RAW do bonus spells cap at 44-45, or have i missed something?
There's an etc at the bottom of the table, so it continues on for higher stats per RAW.
Just continue the pattern.
+1
Just for reference, the pattern is "every time you can subtract 4 and still be equal to or greater than the spell-slot level, you gain an extra slot. So you can just take your stat bonus, subtract the spell slot's level, divide by 4, round down, and add your class's spells per day +1 (from subtracting the slot's level earlier).
Thanks, I lazily looked at the table on the d20pfsrd site which lacks the etc. AON and my physical book have it so thats great.
