Hi John,

Continuing on our conversation, when I asked about the $1 to 10,000 people rule, you explained that 10,000 people is the minimum for a cold audience at $1/day.  Then I asked if it was okay to advertise to 1,000,000 people with a $30/day budget and you said that's fine - the bigger the audience, the better.   So my question is - I remember in one of the lessons - I think it was on scaling - that if your audience is too big and your budget too small, the algorithm struggles to find the top tier 1% segment of that audience.  So...wouldn't the algorithm be struggling at $30/day targeting a million people?  Any clarification would be appreciated, I feel a bit confused :). Thank you!
