Going up to 1M summons for the sake of increased accuracy when ultimately EVERYONE knows "the odds of a black are ridiculously low, don't ever do base summon expecting, or even hoping, for a black. Even platinum is a ridiculous long shot" is kind of wasted effort. The highest unit type people do base summons expecting to get without 1k+ summons is a silver, which is roughly 2-3%
