   Yeah, I'm pretty sure that's it.   
      
   An executable that is only 1.5 MB in size should be   
   optimized so that it can run on a system with a 5-bit   
   segment shift.   
      
   If it ends up running on a machine with an 8-bit   
   segment shift, so be it. That's the trade-off - you lose   
   a bit in granularity, but gain in a lot more memory   
   available.   
      
   But if you're running on a machine with only 2 MB   
   available, then assuming a 5-bit shift gives you   
   exactly what you need.   
      
   You don't gain anything if you force a 1.5 MB executable   
   to assume it is running on an 8-bit shift machine.   
      
   Optimize for the theoretical 5-bit shift.   
      
   And the same thing applies to a 3 MB executable having   
   an implied 6-bit segment shift etc.
