Resistor mod on LD-29 driver

So, doing something like this from this thread is how to do a resistor mod? Looks ok enough. Just don’t know the maths behind it though. I do have some 22 AWG wire from Int’l Outdoor coming my way, so I should be able to use around 5cm for each leg of the resistor to total 10cm, and, from the losses incurred by resistances throughout the light, I could potentially be seeing around 5A to the LED after all?
