dont know about the minimim rise but i think the max tolerance between risers is 5mm. not 100% sure if thats regulation but on any set of stairs ive done in the past its what ive been told by formen etc.

Private Stair any rise between 155mm and 220mm used with any going between 245mm and 260mm or any rise 165mm and 200mm used with any going between 223mm and 300mm

Institutional and assembly stair
Any rise between 135mm and 180 mm used with any going between 280mm and 340mm

other stair
any rise between 150mm and 190mm used with any going between 250mm qnd 320

the norm is
6 inch risers
10 inch treads (thats old money btw )
