1 inch headset or 1 inch headset

[Emerbmx]

Does anyone know what the numerical differences are between a mini one inch headset and a standard BMX 1 inch headset (e.g. a Tioga bear trap)?

People selling (and buying) bearings seem to get the 2 mixed up all the time.
I just bought some headset bearing races (I prefer them to the loose ball) and annoyingly ended up with sets which are about 0.5mm too small.

a shame there's not a universal classification to easily distinguish the different sizes
