My preference, if I was starting over, would be to skip the "Bigger 4" because they take so much time and effort to craft and level it high enough to craft the plus vesion. If/when you get an EB armor, take note of 2 things: base stats at lv 1 and how many points the att/def increases per level. For example: Abominable Platemail base stats are 378/452. If the spreadsheet didn't have the information for it, you could increase it's level and take note of point increase, in this case being 7/9. Take each number (7/9) and multiply each by 69 (number of levels to reach 70) which would be 481/621, and add them to the base stats to see what the max would be. I hope you understand this, as I'm not very good at explaining how to solve math problems:)
