It all comes down to tactics
It must be a guideline simply because no two GMs will run monsters the same way consistently. I'm a method-actor type of GM, who views tactics through the creatures' eyes, which can result in unorthodox maneuvers like Int2 creatures with high DR developing "drop bear" tactics, plus determining when creatures flee and how they flee will vary from GM to GM.
If it were a computer game where the DM just sets up the monster in position then the CR/EL system would be much more accurate and easily tailored. Heck, you could essentially have the computer run a giant death match to determine CRs.
Then there is the fact that some GMs will "misuse" creatures. Or more appropriately, they won't recognize the EL adjustments that are in effect because they aren't the obvious ambush/extra equipment/no equipment/etc. For instance, subterranean creatures are often fine with their short-range darkvision/tremorsense because in a cave you can probably break line of sight in a fairly short distance. That same creature on the surface is almost a joke simply because it's too easy to see targets 100' away even in many forests.
I really wish the EL table had a "fish out of water" entry. Sure, a megalodon is a horror in the sea but beach that sucker and it's just dinner for 200.
