Wat. No idea what you are saying here.
The only RNG element involved with Nades, is this one:
https://docs.google.com/spreadsheet/lv?key=0ApmrrrPr20ncdEpuSHcxNko1VGVFYjczYXpFZWhqOHc&f=true&noheader=true&gid=12
Which states that only on models that have <50% you have a 10% chance for a kill crit.
If 5-6 Nades did "just about nothing" then you must have thrown them somewhere that they did not hit the MG42 models. Has nothing to do with RNG, only with placement.
does it say anything about 100% accuracy? I didn't check the spreadsheets but I think that they don't always land where you aim.
And as Marcus pointed, even tho visually looks like I hit the window the nade still may have missed.
Randomness means that they can miss 5 times in a row (statistically not likely outcome, but with random chance of this happening, statistically it will happen occassionally)
Same way I lost Panther after missing 3/4 times SU85 with just about 0% health because it hit me back every time. (you have to take into account accuracy while moving, terrain, etc. It lowers the odds drastically)
Anyway, don't want to get into this argument about RNG
My question was If anyone here has thrown nade and killed/damaged MG42 inside the building.
so far I got a lot of theoretical explanations
