As an ex-pro CS player (circa 2003-2007), this is pretty neat. Unfortunately, even though CS might have a fairly deep weapon pool, only a very small subset of weapons are actually used in competition (I'd wager 85+% of gameplay mostly involves the M4, AK, AWP, Deagle, and USP/Glock). Situationally, a few weapons would be interesting to compare (the MAG-7 and Scout come to mind), but the tool isn't particularly useful…
What sort of analysis of map positioning and strategies are you thinking about?
