Do you have to wait between Capital One personal and business credit card applications?

I have heard the unspoken rule that you have to wait 6 months between C1 credit card applications. Does that same rule apply to business credit cards as well if I was recently approved for a personal card? Just curious if anyone has experienced a similar situation.

I have also heard about people being approved for two c1 cards on the same day. Has this been the case for anyone? This is just merely curiosity.

Side note, I was approved for the venture rewards card and venture exactly 3 months apart.
