A lot higher than 4-6 wavelengths.  I ran a 10m yagi in EZNEC at 200 feet

QUESTION:  YES- EZNEC GIVES US A GENERAL IDEA... BETTER THAN NOTHING.  BUT 
HOW ACCURATE IS IT?  BUT WHEN EZNEC WAS CREATED JUST HOW MANY ANTENNAS DID 
THEY TEST?  HOW MANY ANTENNA HEIGHTS DID THEY TEST?  WHAT TYPES OF TERRAIN 
DID THEY TEST?  HOW MANY FREQUENCIES DID THEY TEST?  

IN OTHER WORDS, DID THEY HAVE A 10-METER ANTENNA AT 200'?  IF SO, DID THEY 
MEASURE LINE-OF-SIGHT AND FIRST AND SECOND HOP SKIP? 
IF SO, WHAT HEIGHTS WERE THE RECEIVE ANTENNAS AT?  LOTS AND LOTS OF VARIABLES 
HERE... SO HOW ACCURATE IS EZNEC?
