Practice group question

[JonGu]

Just looking over the schedule for Heartland coming up and I'm a bit unclear on the practice schedule. The wording of it is really confusing to me...

For example, on Friday it says:
Group #1- All Amateur 250GP Bikes & All MW Classes

Does this mean Amateur 250GP & Amateur MW classes, or does it mean Amateur 250GP, and ALL MW Classes both Ex and Am?

And then another example:
Group #6- All Even# Expert 250GP Bikes, All MW, HW, & UNL Classes & Supertwins

Does this mean Even# Experts on 250GP, MW, HW, UNL & Supertwin bikes, or does it mean Even# Expert 250GP bikes, and ALL MW, HW, UNL and Supertwins regardless of EX or AM and Even/Odd?

The wording is very confusing, like how in group 1 it specifically says Amateur 250GP bikes, but then it says ALL MW classes, which is ambiguous as to whether it includes experts in MW classes or not. Clearly it shouldn't but the way I'm reading it, it does.

Morning, Jon!

It would not be mixed amateur and expert in those cases.
