[FTC]: What counts as a "stack"?

[alicia635769]

I looked through the game manual but I am still unclear about this.

If a stack of crates is separated by a thin piece of metal, does it count as a stack? In other words, if a stack consisted on the bottom-most crate, then a thin piece of metal, then a second crate, what would score would this get? (Assume each crate has one ball in it, and is upright, open side up.)

At the end of a match, if a bot is holding a stack of crates (not in contact with the ground) and the bot is on the platform, does the 10-point bonus for a stack on the platform apply?
