Column 
Descriptions 
O/E Pattern 
This column will display all the possibly O/E pattern. The pattern is derived
from the hit count of each column. The example above on pattern
42 is actually referring to 4 hits in Odd column,
2 hits in Even column.

Freq 
This is the frequency hit of the O/E pattern.
By default, it is sorted to the highest on the top. 
Last Follower 
This shows the O/E pattern that follow the last
winning pattern in the history. If there isn't any previous winning
pattern happen in history, then there will not be any follower and
it will be a blank space. 
Most Follower 
This shows the most frequent O/E pattern that
follow the previous winning. 
Next Gap 
This is the number of draw interval skipped
since the last winning in history. 
Average Gap 
This is the mathematic average gap of the winning
pattern. It is calculated from the draw range divided by the frequency
hit. 
Perm % 
This is the percentage of the O/E pattern permutation
in term of the whole system permutation. The higher percentage means
more numbers belong to this O/E pattern, hence also higher chances
of hitting. 
Expected Hit 
The is the expected hit occurrence of the O/E
pattern within the draw range analysed. It is calculated base on
the permutation of the O/E pattern. Theoretically, the actual hit
occurrence will be very close to the expected hit rate. 
Bias 
This column shows the differences of expected
hit with the actual hit. If the bias is less then 0, the value is
display as red color.
