Pretty much that ^ is my question (do/should we have an official procedure? I'd just like to help fill a few in that only have ???s in them), and then...
Why are smaller numbers sometimes written before larger numbers? (like the numbers under stratum 5 & 6 for super blaster)
How are damage numbers verified?
EDIT: Thank you.
Not really a procedure, although when testing a weapon it should be at heat level 10 and have no damage bonuses.
The numbers are shown from the first floor of the stratum to the last. For most lower star weapons (3* and under), the damage will go down once you get past its intended tier, which is why they are in reversed order.
They aren't verified and mistakes can happen. However, many weapons have the same damage tables as others (for example, cautery sword and arc razor) so you can see if they match up.
