Details of a correct High-Low test
In my *first* high-low I ran the following sequences:
High Tests:
R67-L57-L57
L57-R67-L57
L57-L57-R67
Low Tests:
R47-L57-L57
L57-R47-L57
L57-L57-R47
During these tests I looked for a widening signature and this worked perfectly to correctly show me that L57 belonged to wheel 3.
My understanding is that you test two wheels with the good number and look at the results of the bad number because if you only tested the good number on one wheel at a time you might not ever see a good indication if the fence is resting on one of the wheels with a wrong number.
So, as I progressed along I knew that my combination was ?-?-L57 and I knew that one of the two remaining wheels was R88. I set about doing a high-low test like so:
R88-L98-L57
L98-R88-L57
Low Tests:
R88-L78-L57
L78-R88-L57
In this scenario shouldn't I be looking for a *narrowing* signature? If I understand the workings of a lock correctly, moving two wheels into correct positions should narrow the signature whereas if there are two wheels on wrong numbers and one on a correct number (wheel 3 on L57) the signature should be wider. I've never seen this specific issue come up on any of the other forum posts and just wanted to be sure before I throw away a bunch of time. Also, if this assumption is wrong, I'd really like to understand why it's wrong because it really, really seems right.
Thanks a bunch!
