What are the stat requirment to reach high end range?

The intention was to figure out how much more %Main stat and watk I need to get somewhere near these high end ranges. I have rough idea how much self buff will boost my range but I don't have much clue about the raw stat I need.

I didn't want to ask buffed range because by buffed it could mean all sorts of buffs such as TaC, pots or even apples! Which will then eventually become a question of what buffs can be stacks together to boost one's range.

For classes other than DA and Xenon the range formula is simply: (4*Primary Stat + Secondary Stat)*Attack/100*(1+Attack%)*(1+Passive damage%)

Just work out what total Primary stat you need by fixing secondary stat to 2k or something and attack to 1k, 1.5k, 2k.
