Yes i think i said on another thread it is about ELO 280 perhaps.
The ELO of the computer here is about 20 as i'd expect even people who have never played and just spent 2 minutes reading the rules to beat it 4/5.
The failings of Probe are predictable movements . An important piece is always backed up . If you reveal a Colonel on your front row and Probe puts on unknown piece next to it you know it will be the Marshal or General , never a bluff .If you threaten Probe's known General,Colonel or Major with an unknown piece it always backs off .
Also it is quite inept at defending an open flag, you can sometimes just march a Sergeant straight to it in the middle of the game.
It doesn't give up important pieces (other than sometimes the flag ) for nothing though and if you reveal your Marsh and Gen too cheaply it will attack your other pieces quite efficiently .
