The stats numbers used to be more precise, but they got simplified in one of these more recent updates. I know there should be exact values hidden under these perfect whole numbers. I know there should be a small difference between the reload times of a lvl 2 and lvl 3 dragoon, but there is none. Instead of using the real reload time, hidden under the nicely rounded whole number, the game uses the rounded up number as the reload time.
The 2nd picture shows no difference in reload time between a lvl 2 and lvl 3 dragoon.
