An ammeter in series is useless, because it shows consumption, not location = tip failing to heat..
For me it is a waste of time.
45 minutes once per year to remove, examen, glow test, reinstall = "priceless" to never fail cold starting.

Which milliohm meter do you own? The $500 or $5000 one?
FYI, I doubt there are more than 3 forum members who own a milliohm meter.
Why won't you discuss/argue the useless readings "used Glow plugs" give.?
I'll have to disagree with you that an ammeter is a waste of time. You are correct that it measures consumption, not location. If you take a look at the construction of a glow plug (see pic), the only way the tip does not get hot is when there is a short at the junction the "heating coil" and "regulating coil" near the tip to the case, and the ammeter will measure a different current (higher) than normal, that is the time to pull it to test in a vise. An ammeter will save you time and the trouble from pulling all glow plugs to test in a vise, a miserable and unnecessary job.
