Stars 180 SNG Payout schedule

I have played in 3 of these, and came in 6th, 3rd, and 71st (KK lost to AA). I just figured I was running good to hit 2/3 final tables, and I just kept playing the regular 22s. Maybe I should start focusing on these if everyone agrees they are soft. Can anyone explain why they would be softer than other tourneys?
