your tracing is accurate
"20 by 10" has something to do with verses like this:
Luke 14:31 "what king, when he sets out to meet another king in battle, will not first sit down and consider whether he is strong enough with ten thousand men to encounter the one coming against him with twenty thousand?"
the biblical number '10' symbolizes/represents the spiritual servants of the wicked one, while the biblical number '20' symbolizes/represents the spiritual servants of the true God, so "20 by 10" symbolizes/represents the system/kingdom of the "beast(666)", which is based on the satanic kingdom but tries to use one third of the "heavenly stars" in its own favor (33.3% of the heavenly boon based on 66.6% of the satanic kingdom), which is why unrighteous religions could offer their followers/worshipers a great bliss, sublimity, grace, power, glory, and other suchlike (as it were) "heavenly stars", but such a spirituality/religiosity is a greatest abomination/defilement on a world scale...
