I started out with fractional riser heights all the way up from ground level but the landings only go by the rounded inch. How were you able to set the landings? In the end I had to go with 4" risers from bottom to top so they were all the same at 4". In Alt-3 that is ok but im sure the test would be tighter and would not allow for this

There's no need for even inches. Why would anyone think so?
The best way to determine the number of risers required per flight is to take delta between landing, divide by 7, and round up.

1. Even inches makes for easy math. Why use rounded inches or fractions?
The exact riser height is irrelevant. You should be estimating (or fixing a min based on what's below) what a good intermediate landing height would be and providing risers per above.
2. Why divide by the number 7?

I'll let you think about that for a sec.

Riser height may vary between flights.
