The first thing that seemed to appear was that once you learned a new rank of a spell, the previous rank suffered a 5% downranking coefficient and then a further 5% for each additional level. Unfortunately there were a few anomolys that did not fit this perfectly.
The most obvious one was Holy Light Rank 9. Now, for Holy Light, new ranks of spells before wrath have been learned every 8 levels. This spell was one of the AQ learned spells which broke this pattern. Rank 8 was learned at 56 and rank 10 at 62, but due to this extra spell (level 60), it meant there was only a 2 level gap between it and the next rank up. According to the rule i've stated it should start downranking at 62, which it doesnt.
However this can be accounted for by the following formula:-
Downranking coefficient = 100% - 5%*(Current Level - (Spell Level + Common Levels Between Spells - 1)
When I say "Common Levels Between Spells" I mean the general rule of thumb of how often a new spell is learnt. For Holy Light and Flash of Light this value is 8 (and is variable depending on the spell used).
Using this formula, it fits all spells (see exception), including the AQ book learned rank of Holy Light. Holy Light rank 9 doesnt start downranking at level 62, but instead at level 68.
Exception:-
I'm only level 74 on beta, so have only managed to get a new Rank of FoL so far. I did notice however that the moment I got this new spell, my previous spell downranked by 10%, not the expected 5%. Now, my one possible explanation for this is that to avoid current max rank spells being more powerful than they would like in wrath, they are doubling the downranking of current max rank spells so that.
Downranking coefficient = 100% - 10%*(Current Level - (Spell Level + Common Levels Between Spells - 1)
As I gain more levels and get more ranks, will test it out.
Let me know if this fits any of your beta tests.

I've got the following data for Arcane Missiles with a 1% exactness, from a level 75 player:
(A new rank is learned at level 75, Arcane Missiles before 60 are learnt every 8 levels, at 8, 16, 24, etc.)
The testing suggests very strongly that penalty scales in 5% steps.
I added a "Level" number at the end, which would describe the last level where the spell would get full scaling.
After that, it would lose 5% per level. This part is speculation though, since I cannot do any kind of reliable testing.
I only know the scaling at 75, the "last level" concept is a guess which would fit the data.
Rank 11, learned at 70; 80% power => Level 71
Rank 10, learned at 69; 80% power => Level 71
Rank 9, learned at 63; 75% power => Level 70
Rank 8, learned at 60; 55% power => Level 66
Rank 7, learned at 56; 35% power => Level 60
Rank 6, learned at 48; 0% power => Level would be 55 or lower. Level 54 would fit.
I would need something like another set of Arcane Missile data from a mage who is not level 75 to confirm this concept.
The big question that remains however is how the listed "Level" is determined.
It might be the last level where the spell gets a base damage/healing bonus, but I know no mod/database that tracks this information, ot tracks the level-dependent base damage.
For Arcane Missile, it seems to be "level learned + 6", with A'Q/BC spells not exactly following that pattern and pre-Wrath not reaching far past 70 (even the the spell learned at 70 only seems to count for 1 level).
It may also be that the level 70 gets full benefit until 74 because it's the highest spell at this level, and at 75 suddenly drops by 20%.
Might the penalty based on actually learning the spell?
Warlocks have only 1 rank of Chaos Bolt taught at 60 (new ranks should be expected at 70/80), the others ranks are simply not there yet, and the spell also gets a penalty.
My question for your Flash of Light of test would be:
Did you check whether your old highest-rank FoL still got 100% at level 73?
