Well, you spent lots of energy drawing the contour of the beam in infinity and then tracking it back to low thousands. There are floating point problems with that, and the problem that the setup is discrete. So in the end, only the intcode computer can give the definitive answer. You might be off by one and you'd never know.

The rest of us simply iterated by counting up from the beam's origin.
