Facade from 'Mask of Humanity'

[Icelander]

'Mask of Humanity' is an article by Cristopher R. Rice in Pyramid #3/97 Strange Powers. It provides rules for a supernatural force which prevents mundanes from noticing, accepting or remembering blatantly impossible phenomena.

I'm using these rules in my campaign, but haven't yet featured a character or monster with the Shrouding skill or used the table to calculate a Facade rating (usually I assign one based on how mundane or spooky I feel an area is at any given time, from 0-20). So I hadn't noticed a couple of issues before.

Also, no PC has failed a roll in play, it's mostly a narrative device to explain NPC behavior.

A) Why does darkness give a bonus to the Facade and good lighting also give a bonus? Shouldn't either of these things give a penalty?

B) On the Initial Response, why is it much worse to fail by 2-4 against the Facade than by 5-6, or even by 7-9, or, for that matter, than the results of most Fright Checks? Berserk for minutes or hours is orders of magnitude worse than Dazed for seconds or even minutes, arguably even hours.

Subpoint to B), the table lists 5-6 and 6-7 as line headings. 6 can't lead to two mutually exclusive effects (the same effect can't last seconds instead of minutes while it lasts minutes instead of seconds). How should the effect categories be broken up instead? Where should 6 fit, is the next category just 7 or do we change it to 7-8 and then change 8-9 to just 9? Or should 5-6 become just 5?

C) I don't see any modifier to Shrouding skill for the local Facade rating. Is Shrouding meant to work equally well in areas with weak Facades as strong ones? Because that would seem contrary to the narrative description of using the Facade to shroud you.
