My vote on this report is NO because the delay itself is not hardcoded, I've viewed all the replays and can conclude that dropping 2~3 meds in one go is just a mechanic glitch not a med hack, for instance I recall when I used to play snipers, that I can triple scope, which was the same concept. Also when dashing the meds will drop faster than at normal speed.

Also I remember viewing other players after Zeus died in his rounds, and they were able to accomplish the same feat as Zeus and drop 2~3 meds in 1 shot, mostly 2 but the occasional 3.
