Hey, I was on my honeymoon and not reading emails, nor receiving any notifications which comments like this are not presented in the UI of any editor I use. So I don't have any indication except email that a comment was made for me to respond and those are filtered out for me to check when not busy with other things. That is why there was a delay.

Yes, the Plastic numbers refer to the resin type accepted. The numbers are what are posted, converting to name is a cognitive load I didn't apply and I think it may have been a suggested response at that time in ID IDK. There needs to be an equivalency for the values so users don't have to remember what number corresponds to the value and/or conversion. Its been too long for me to recall why they were entered that way, but they can be fixed and/or standardized.
