My understanding is that every Bitcoin client has the same algorithm (formula) built into it to automatically adjust the difficulty every so many blocks.
Then how is it dependent on how many CPU’s are connected to the whole network?

We need Satoshi to confirm that because clients accept blocks generated at easier difficulties all the time whenever the PoW’s difficulty increases.
