having connectors with a cross section larger than the wire itself doesn't make much sense.
then 8mm bullett is overkill.
This is true IF all conections are clean and properly soldered or grease ( residue from your flexcable you just lubed) contamination is not present.
This does not happen at all times, sometimes fingerprint oils can be existant on said connectors.
Many times connector prongs have low tension, microscopic corrosion (fretting) or carbon build up resulting in a 8mm connector acting like a 5.5mm connector.
To compsenate for "real life conditions" does make sense.
