Numbers are accurate. I'm not worried though since you didn't list an important note. The numbers are only if you dont have any higher grade materials. We dont know all the sources on how those can be obtained yet. Maybe we'll get them from nightfalls and raids? I know we get some as seasonal rewards as well. Maybe crucible resets and gambit resets grant some as well? By the end of this season, I wouldn't be surprised if I have a full armor set or two for each character.
