Pippin:
Ah, someone else has noticed the clue that points straight at 
EverSoEvil!Lupin.

Lupin is obfuscating. He  *must* know how much potion he needs 
to take, or it would hardly be safe for Dumbledore to let  him spend 
his transformations curled up in his office -- he'd need to be
confined in the Shrieking Shack or some other place that even those 
experts Fred and George couldn't break into. Teachers' offices, we 
are reminded once again, are not secure.

The extra potion makes it possible that Lupin did indeed take his
required dose on that fateful night, nipping down to Snape's office to
help himself from the cauldron, then dashing out to the Shrieking
Shack. In which case, Pettigrew's escape was no accident.
