Never heard of that site but the question is whats that "potential" based on?. making a comparison between a 513 sam and a 530 sam for example is pretty useless at best. this is where fflogs doesnt always paint an accurate picture...
what imean is for example one of the top samurais in diamond weapon is 23,269 dps. that number on its own doesnt equate to a whole lot. while i might assume hes full BIS samurai it still doesnt tell me anything usefull. my 39th percentile parse was like 21,116. so there's a 2k dps difference. but again that doesnt tell me very much. because i was i513 so there's obviously going to be a significant disparity but its unquantifiable exactly how much that disparity is or rather should be. (not to mention impact of party compositions or whatever.)
This is why i said any improvement tools should work potency more than damage. because its a much easier value to work with and comapre.. using potency per second for example i might find im right on the tail of that number 1 samurai "wishful thinking" and get a much better representation of my performance in a metric that eliminates the variable of gear.. and the less variable you have the more accurate and actually useable the information is.
measuring based on damage is largely useless as an improvement tool because there are no quantifiable ranges or measures because of the huge number of variables. a sam doing 15k dps for example means nothing if thats all the informantion you have. if hes doing 15k dps at i430 its a completely different result than doing 15k dps at i530. damage needs a reference in order to be comparable or accurate.
to reference the diamond run i mentioned for example. 21,116 dps. is that 70% of what i could potentially be doing at that ilevel
or 95% of what i could potentially be doing at that i level
thus the informantion is useless. its just a menaingless number without something to measure it aagainst or a point of reference
I could for example say Oh hey i'm giving you a 5 for that site you mentioned. is that 5/5? 5/10? 5/100? 5 on its own means nothing without a reference to measure it against. damage is the same.
which is why a self imrovement tool that worked of potency would be much more usefull. because shinten is 320 potency whether your itlevel is 430 or 530. so it becomes much easier to compare and is much more usefull then.
Edit. Checked xiv analysis but again that doesnt give you anything to measure against. though it point out a couple of rotational balls ups (something to consider at least) but it still doesnt give you a point of reference in terms of how you measure up against a potential.. so agian i could be doing 70% of my potential for my current ilevel or 95% you just don't know.
