Re: The YEC should be considered a fifth major
To win a Slam you have to beat 2 or even less top 10 players. To win YEC you have to beat 4 top players. Moreover, you have to qualify for YEC. Just looking through YEC winners and Slam winners during the last 15 years it's obvious that winning YEC is tougher task than winning Slam , but it's still less prestigious.
Technically you can win YEC with 3 wins and 2 losses. SF And F wins can be walkovers/retirements too.
