getting a new mouse

[Dimetime35c]

im getting a new mouse to replace my g502 sense sadly all the feet pads came off:( im looking at this one http://www.razerzone.com/gaming-mice/razer-mamba-tournament-edition. mainly cause its the only 16k dpi mouse i can find and its only 90$. the only thing i dont understand is why does the mamba with a higher dpi and better sensor have  210 inches per second / 50 G acceleration, and the older g502 have Max. acceleration: >40G Max. speed: >300 ips? i really like the mamba cause of the 1 dpi adjustments and the chroma lights.
