This refers to your query on over crowning and SF.

 

It is not necessary to have more SF when there is a over crowing.

 

Over crowning and SF are different items and need not be clubbed.

 

1    There is a tolerance in section VIII div 1 for over crowning.Total height will go up if there is over crowing..

2    If the SF is more then the Total height will go up .

We are not suppose to combine the both.

Because

SF starts from the top portion of knuckle radius.

Crown radius starts from the bottom of knuckle radius( i.e end of knuckle radius crown radius will start.)
