OK, we took a look at it and while both compared effects had density of 15 (and both used just 1 model and that model had in both cases all 16 points of importance from 6-9 fields - both effets exactly the same setting. just a different model ID used) and damn, those WoD models really do behave strange like hell. While HF ones did what was expected with this setting, they just cowered everything really densly, WoD model was not that dense and more importantly, it was clustered. Like density was around 100, not 15. Very strange behaviour indeed. Someone knows what to do with this, or by what it might be caused?
