200 Watch - ETAs for GMS

Hey i was just wondering how this list was working, i see on it that some people are listed starting on like the 12th as opposed to liek the 5th that most other people are listed as and i was wondering how it is done that way, liek i was on the list a few weeks ago for Beran Pirates and then i went to my KoC so i dropped off but like i came back and its still taking my exp from the 5th of this month when i didnt train my corsair @ all till liek 4 days ago... i just figured that it would be takes from that point onward and if so why isnt it kinda thing.. cause atm im listed as having gained like 36M exp on avg per day when in reality over the past 4 or 5 days ive gained at least 100-150M exp a day ... just seems kinda wonky to me... or is it keeping me as a record of having been on the list before so it keeps reading it from then.. which i would understand
