The lack of precision does matter when we are talking about trenches/bunkers and bombs often missing by many dozens and even hundreds of meters.

Unfortunately they don't miss by hundreds of meters. And Russia frequently uses 3000lb and 6000lb bombs. So missing a bunker a bit doesn't matter - it will still collapse. Here for example it is clearly visible that the bomb misses the building by about 20m https://t.me/RtrDonetsk/25282
