...the quote from Arcane Arrester doesn't actually say said magician can add up to 5 hits for casting a Force 5 spell even though the damage is being resisted at Force 2 instead. It's easily arguable that only up to 2 hits could be applied against the character with Arcane Arrester.
The point is: Force is not reduced. Only effects of the spell that are based on Force are. Hits rolled during the Spellcasting Test are not an effect of the spell.
QUOTE
Note that the actual Force of the spell is not actually reduced.
Anything else is just wishful thinking.

QUOTE
For instance, a character with Arcane Arrester targeted by a Force 5 spell would resist it as if it were a Force 2 spell, though the spellcaster could still add hits to improve the effect.
When you resist the spell, you roll your dice against the hits scored on the Spellcasting Test. The Spellcasting Test has already been done at this point.
The target resists the spell as if it were Force 2, but the mage still treats it as the Force 5 spell that it is, because the actual Force of the spell is not actually reduced.
QUOTE
The hits scored on the Spellcasting Test may not exceed the spell’s Force (see Force, p.177).
There is only one answer to the question "What is the spell's Force?".
In case of a Force 5 Stunbolt cast on a gnome, the answer is the same as when a Force 5 Stunbolt is cast on a dwarf. The answer is "5".
The gnome has nothing to do with it. It's just the mage and the Force who are relevant.
So, the hits scored on the Spellcasting Test may not exceed 5 (in this example).
It becomes even more clear, when you branch out into area spells. There is only one number of hits for one spell. You make one test, you record one number. If you cast a Force 5 Stunball against the gnome and the dwarf, and you roll 5 hits, than that's what you have - a Force 5 Stunball with 5 hits. The dwarf gets hit by a Force 5 Stunball (with 5 hits), and the gnome also gets hit by a Force 5 Stunball (with 5 hits), but he resists it as if it was a Force 2 Stunball (with 5 hits; the spell is still Force 5, only the Force-based effects - base DV in this case - are calculated as if the spell was Force 2). You cannot have two different amounts of hits. The Spellcasting Test can have only one result and only one limit for this result. And that limit is the Force of the spell - the actual Force.

That quote should be more clear now, hopefully.
It's a Force 5 spell, which allows you to score up to 5 hits on the Spellcasting Test. It is resisted as if it was a Force 2 spell (with 5 hits). The spellcaster can still add the hits he scored in the Spellcasting Test to improve the effect. The reduced Force (which isn't even actually reduced) has no effect on that.
Important note: The limit (from Force) is
not how many hits you can add to the effect against the target (which would surely offer some room for this argument). The limit is how many hits you can
score on the Spellcasting Test (and that leaves absolutely no room... you can score as many hits as the spell's Force, and the spell's Force is 5; it's a constant value that does not change).
And as a side note: Why would they even mention that part about adding hits? Is it something special, that you can add the hits to increase the effect of the spell? Not really, that's just standard procedure. Mentioning, that you can do so, is pointless and redundant. The existance of that part only makes sense to point out that the full hits can still be added (to the Force of the spell, which, as already mentioned, is not reduced by Arcane Arrester).
Bye
Thanee
