If you want to get better measurements, forget using your ammeter scale. Put a very low ohms resistor in series with each LED. I found a bunch of 0.1 ohm 2% resistors at a surplus store and bought about 20 of them just to have for this sort of thing. Then just measure the voltage across the 0.7 ohm resistors.
Odd that, I thought that was exactly how a multimeter is wired inside for measuring current.
