Offensive grenades should have a lower HEK with 1 PEN

If the designers went with generic grenades, then perhaps they should all get something like HEK 5 PEN 1

Why assume "poor quality" of F-1? There can't be much philosophy in creating a pre-fragmented cast shell and 60 g of explosive inside, especially, that it was a copy of the French design I would suspect, that it would rather be prone to malfunctioning, instead of being less lethal.
Official manuals consider safe radius 200 m, on the Russian Wikipedia they quote examples of injuries at 70-80 m for own soldiers without good cover.
