Seriously guys if you Sherdog record isn't correct get it updated !
If you are missing 3, 4, 5, 6 fights on your records and they all come from 1 or 2 shows then DO NOT fight on there. Or make that promoter database their results.
End of the day if you care that little about your career then how can you expect anyone else to care too. It's the same with promotions too, people should be outing this kind of behaviour.
