One pass Large Pitch Raises Safe?

[Andrew & Rebeca Anderson]

I've been following a discussion regarding a large pitch-raise of 100 cents 
or more being done in one pass.  Is this safe?  Do you run the risk of 
damaging a plate by, say, concentrating tension in one area as you begin to 
pull the pitch up.  I'm not talking about strings which are risky in their 
own way.  I've understood that when there is such a large tension 
adjustment to be made that it is safer to spread it out as octaves, such as 
all the A's then all of the E's then all of the C's, then fill in the rest 
after which you do a fine tune.  Am I being overly cautious?
