![]() If they are far enough apart, then the SerialBot assumes this is a gap. If they fall within a certain threshold then the SerialBot assumes that there are valid serial numbers between the two. It groups the serial numbers together based upon how close they are to the next serial number in the sequence. If you see a linear coverage number that is higher than the known production run, it is probably not the best way to look at the serial range and you should look at the clustered approach below.Ĭlustered: Clustered coverage assumes that there are gaps/skips in the serial sequence for a game. However, this approach starts to fail quickly for games that serial numbers are part of a bigger numbering scheme (Williams pre 1984, Current Stern) or that intentially had gaps/skips in the numbering sequence(Gottlieb post 1960). ![]() For some games, this works fine because the serial numbers were sequential and without gaps (Early Bally, Early Stern, etc). ![]() Linear: Linear coverage simply looks at the highest serial number and subtracts from it the smallest serial number to estimate the number of games produced. There are two coverage methods shown, each has a different approach of calculating an guess on the number of games produced by analysing the currently submitted serial numbers. ![]() The term 'coverage' relates to the amount of the production run that has been 'covered' in the given submissions. Coverage is a mathematical interpretation of the serial numbers that have been submitted so far. ![]()
