S!
Viikate, if you read what I wrote the fragment pattern is most effective at close range and they disperse very fast and small fragments lose their energy faster than bigger ones etc. Quite a lot of factors to take in account, we did calculate those in EOD training
Also remember that the big bombs like 250kg or above did not explode on the surface but slightly below it as they did penetrate ground before fuze did fire the explosive. Some lighter bombs like 50kg and 70kg had the "rod fuzes"(found no better word quickly) that made them explode near or over the surface to maximize shrapnel effect. And yes, I would have stood there 300m away even the 2.5kg PETN would have been in a casing. Well beyond the dangerous radius
Anyways, a PC game can never simulate the complexity of armament, just some things of it. Add to that my work in military and voilá..you get the pic
