Description
It's not completely clear that BOT is "the moderator" (the instructions say so but I'd like there to be a closer connection), plus we may do human studies so let's rename BOT to MODERATOR.
The last two questions asked of the offline bot: "Did the moderator understand your point of view" and "Did the moderator convince you to change your behavior" aren't answered well by "very" or "so-so"
I suggest changing "very" to "yes", "Somewhat" to "Mostly", and "So-so" to "Somewhat". Then given the answers "Yes", "Mostly". "Somewhat", "Mostly not", and "Not at all" i think the following four questions (note slight rewrites) will be all answerable by those choices:
"Was the moderator coherent?"
"Was the moderator responsive to what you wrote?"
"Did the moderator understand your point of view?"
"Did the moderator convince you to change your behavior?"
