Biggest thing is what the tip looks like and checking the gap with a flat feeler gauge.
The 100k change interval is based on best circumstances, the guys that monitor their plugs across the EB line over the years have found that realistic plug maintenance intervall is more along the line of 60-65K at which point they need to be cleaned/re-gapped or replaced.

Plugs will go 100k miles. Changing them at 50k is a waste of money.
Incorrect, plug wear varies by engine, fuel and driving conditions.
They will go 100k under "normal" operating conditions, however if you look in the owner's manual under the definition of "severe" service you'd be surprised to find that most owners fall into that category.
