Ok, here are the results of a hasty analysis for all remaining players.

Kagemusha

Activity level down. Post length averages about 150 characters; normally above 300. Averaging 2592 minutes between posts, which is well above normal. Activity level was also low in Mafia I when guilty, but relevance of that game is questionable.

Sasaki Kojiro

Difficult player for Holmes to read. Activity levels have varied throughout his many games; this time everything looked normal until his recent absence. Has been jumping in a little quicker than usual – average delay is 90 minutes, when it is normally over 200 minutes.

Stig

Not many games to compare. Activity levels similar to Midgard Saga; posting is a bit less frequent (average 611 minutes between posts compared to 350 previously). Post length also down a bit; 165 character average compared to about 200 baseline.

Ichigo

Statistics look very normal. Post length, as usual, averages about 200 characters. Posting interval varies but looks very close to baseline. His activity level normally appears to drop when guilty.

Pannonian

Average post length close to baseline of about 600 characters; up only slightly. Average posting interval also close to recent baseline (from Capo), which is 300-400 minutes. Jumps in much more quickly than usual – posting delay is 141 minutes compared to a baseline of 600-800 minutes. Has explained this to my satisfaction.

Crazed Rabbit

Activity level down considerably. Average post length slightly higher than usual, but not enough to raise suspicions. Statistics look very close to those set in Interficio, except for posting interval, which is very high. Semi-lurking, which is unusual. Explanation desired.

Reenk Roink

Activity level close to baseline set in games when innocent. His activity level normally goes up notably when guilty. Has never been one of my top suspects in this game.

CountArach

Post length down (90 characters compared to baseline of 126-215 in previous games). Somewhat less frequent posting also – average interval is 1122 minutes compared to 500-700 in previous games. I was suspicious of him near the beginning of the game for some reason.

ByzantineKnight

Behavior varies from game to game, but nothing jumps out numerically. Mostly short, relatively infrequent posts; comparative activity level up slightly (as compared with other players). No real indication of guilt.

AndresTheCunning

Only a few games to compare. In Capo, average post length was 722 characters, average interval was 648 minutes, average delay was 1048 minutes. In Midgard Saga, average post length was 569 characters, average interval was 321 minutes, average delay was 533 minutes. Current activity level much closer to Capo, with an average post length of 937 characters, an average interval of 994 minutes, and an average delay of 1084 minutes. Activity suggests less frequent but more well-thought-out posts. Very likely to have a role.

Dutch_guy

Statistics look very normal. Activity level typically low, both in post length and frequency. If he’s guilty he’s doing a tremendous job of looking normal.

Kommodus

Posting frequency notably lower, while average post length is a bit higher (940 characters) than normal (500-900 characters). Activity level was up in Graffiti Mafia when guilty. Has claimed RL to explain absence.

Ugh, I really need to go to bed.
