Province Bonus to Magic School?

I wasn't sure bout the discount.
However if you're using it like that, give 80S and get 100S in return, you'll still be losing gems until more wishers stack up due to alchemising right?
So it's either 80S for 100S? or 80S for 150 all + 25S? Which I guess in principle would add up the same as you're giving/getting S gems on every turn, and you get all types 1 in 2 or 3 turns, but with the exception that 80S for 100S will grow and give you a much bigger S income over time and eventually bring more gems.
But that still isn't game breaking.
