>>To find the sticky numbers:
Pull on the shackle (the u-shaped bar) while turning the dial. You will notice
that it occasionally clicks into place, leaving only about a millimeter or so
of wiggle room. This is a sticking point!
There are, however, two types of sticking points:
1. The dial will wiggle between two lines - eg. it stops at 21 and 22.
2. The dial will wiggle across one line - eg. it stops at 14.5 and 15.5.
The way we really want to think about these points is where the 'midpoint' of
the wiggle space is. If it is the first type, the midpoint will be at 21.5,
for our example. Likewise, the second type will have its midpoint right at 15.
There should be twelve sticking points total, five of which are the latter
case. These are the ones we want to use! The other seven can be disregarded.
Also of note, is that when the correct five numbers are found, exactly four of
them should have the same final digit.
>>What's the deal with this thing, anyway?
Given the sticking points and a bit of simple math, the number of potential
solutions to a given lock can be reduced from 64,000 to about 80. Now you
don't even have to do the math yourself!
Unfortunately, the combo-testing robot is still in alpha, so you will have to
try the remaining combos by hand.
