A quick question about Child Pays For Parent

[cagriari]

So the tx's are like this:


X --> me
   --> someone else

me --> Y
      --> me

me --> Y
      --> me

me --> Y
      --> me


Is Child Pays For Parent going to work? How to calculate it?

Total 1583 bytes, and 0.00505 BTC fee. Average of 319 sat/b.
So with CPFP, if it's ~1800 bytes and 0.01 fee, it becomes 555 sat/b. Is that how u calculate it?


EDIT - It worked, so I saw that it works on chained transactions.
