After he was done with the pump he thanked me, and I said something like

CO2 versus carrying an infinite supply of air via a tiny pump like the
Topeak Micro Rocket, which weighs 65 gm versus two 16 gram CO2
cartridges (117 grams), since you still need the CO2 inflater.

The logic is pretty simple. The CO2 will work a lot faster than a
little hand pump.
The hand pumps can be quite frustrating to properly fill a tube.

That's why you get the Topeak Road Morph and not one of the cheap ****e
pumps.

Now the logic on measuring things to the gram is something that
escapes me.

As long as their not measuring they're input and output the same way, it
doesn't seem very useful.
