I realize that it is different for everyone, but what is a reasonable expectation for improvement from year to year? I recruited two point guards at around 465 and have no idea what they could potentially end up at over time. Is 25 a year a lot? Do they improve much during the season or mostly in the off season?

It depends on the FSS. It will tell you if they have Low, Average, or High Improvement in each area.

Low 0-8 over the course of 4 years
Average 8-16 over the course of 4 years
High 16-24 over the course of 4 years

I think I got the numbers right.
Here is a couple times from D3 at the end of the season take a look to see improvements.

They can give you at least some clue. When you get a letter at the end of the preseason games it will say each players increase for each category.

Jerry Casares:
defensive fundamentals: big upside
durability: big upside
perimeter shooting: limited upside
rebounding: limited upside
speed: big upside

Big= High, Limited= Low, and if its not listed it means its average
