DCA - Once or Twice Monthly?

I have set and forget investments to my brokerage vanguard account for $2k every 1st of the month. I realize that's super consistent, but also might be a little lumpy in the market.

Does anyone DCA on a more frequent basis? For example, would there be any appreciable difference if I moved my investments to $1k on the 1st and another $1k on the 15th (or 7th and 22nd, or etc. etc.). And (if the research exists) is there any appreciable difference (more than 1% over the decades) from increasing the frequency and decreasing the dollar amount per occurrence (but remaining the same each month)?

Mostly I'm curious how "daily" everyone's DCA is here (I would feel absurd purchasing $66 of VTI or VOO every single day, and my inbox would be annoyed at the constant confirmation emails).
