The records on Wikipedia are relative. Any kickboxing record is relative if the fighter didn"t start in a major promotion. This happen because there is no database. In MMA is pretty much the same but people can build their records better from the internet press. In the United States, any MMA promotion way smaller than Bellator for example gets more attention. Even from 10-12 years ago. In Europe is hardly possible if it"s very old, more than 7-8.
Ghiţă doesn"t have included the amateur record for example. Levin has both (amateur and professional) on record - combined. And other records are simply added on graphics from coaches"/sportsmen"s mouth. Maybe some can confirm with a paper.
The logical analysis would be:
Tyrone Spong: his 89-5 Glory record includes only 5 defeats and not 6 because one was in shootboxing. And some wins weren"t added. If Spong or his coach didn"t lie.
Van Roosmalen: Glory didn"t add his shootboxing and muaythai (thaibox) records, even though the so called Muay Thai or Thai Box Dutch events were actually of kickboxing. Normally they should add any PROFESSIONAL muaythai record (amateur muaythai not) on his kickboxing record. Shootboxing not.
Nieky Holzken: some wins weren"t recorded by Wikipedia, if nobody is lying trying to add some more wins and I don"t think so.
Petrosyan is pretty much the same.
By the way, I can tell you a lot of MMA events which take place in Europe (Germany, Serbia, Hungary, Romania, Russia, etc.) which are not added by Sherdog. Sherdog is pretty much the same as Wikipedia. Nothing really official or if they get official results they get only from the USA. Boxrec is good. That"s a real database. Every fucking boxing result (professional events) from this world. Since "ancient" times.
