So, like so many rookies before me, I've been putting in a lot of hard time on Richard Reid's BC/PE/IC analyzer in search of a better mousetrap. Specifically, I've been hell bent on finding a level one system that gets close to Hi-Opt II. I imagine that thought alone bores the hell out of most people on this site, but for anyone who cares:

Here are the results of sims on an unbalanced level one (true) count that appears to come close to Hi-Opt II. I am making that statement crudely, based on 1) How it measures up in terms of PE and BC, and 2)How it performs compared to HiLo. First, the tags:

2-7 = +1
T = -1
Side count the aces

Next, the predictions:
BC: .98 PE: .65 IC: .92
As a reference, Hi-Opt II:
BC: .98 PE: .67 IC: .92
and good old HiLo:
BC: .97 PE: .51 IC: .76

The sims bring back the kind of SCORES one would expect:

WiWo	        5/6D	 $107.51 $121.00    13%  

WiWo	        4.5/6D	 $64.76  $72.97     13%  

WiWo	        4/6D	 $38.59  $44.14     14%
(technical specs at the bottom of the post)

The Bottom Line
Compared to Hi-Opt II, this system gives up the convenience of 0 as the IRC in exchange for the luxury of a level-one count, while achieving comparable SCORES. I have little real-life experience counting, so my question is, isn't that a very good trade off?

Technical Info
Sims were done on SBA 5.51, and optimized for a 1-10 spread using SBACALC.
All games were H17, NDAS, NS, FU
Both HiLo and Precarious sims were run using full indexes.
Wong In @ +1 speaks for itself (no wonging out)
WhiteBunny is a variant of Schlesinger's WhiteRabbit, wonging out at -2 for first 1/3 of the shoe, -1.5 until 3/4 shoe is dealt, then 0.
WiWo does both.
