It is likely that the exact steps you take for catching tyrogue will differ from catching beldum. This is due to random frame advancements occurring from walking and the 128-step counter being tripped sometimes. No matter who you're catching, you will have to calibrate each time when doing radar abuse. Also, try to remember EXACTLY how you walk when going about this (like do you pause at all between steps/turns).
For starters, try getting to know what your seed's patch arrangment looks like, then go into one of the patches and see what pokemon you get. Catch it and figure out what frame you hit. Depending on your target pokemon, the patch can be either common (green and shaky) or rare (white splashes in the grass). Pokeradar exclusive pokemon seem to only appear in the rare patches. Is tyrogue rare/radar exclusive or swarm? Beldum can appear in common patches or rare; I used a common patch for mine.
