I have randomly entered number pairs below.  I have seen this done on both pick 3 and now pick 4.  The way I see it, these people are either too lazy to enter in the extra 1 or 2 numbers,  or they really have nothing and basically are flinging crap at the wall to see what sticks!  I wouldn't be surprised if some lazy idiot posts pairs for pick 5 now!

This is the correct way to post pick 4 numbers:  6930 9971 1997 9049 0649 and these are my picks for tonight I won't be actually getting a ticket though. 

This is how to post pick 3 numbers:  546 676 257 563 463
