Address added to my list
@WanderingPhilospher nice to test this again, but just like someone said before you don't need to do it, unless you want to test some specific thing.
You can also organize a bait and at the same time you can run a real transaction for 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so. That would be fun.

I also think the same when the Brazilian guy did his experiment, that is why i develop my bot to what multiple address at the same time.
Child Pays For Parent (CPFP) in Bitcoin what it does in practice
When a UTXO is not confirmed by the network but you need to pay something ASAP you can increase the fee of your transaction just to push the miner to accept both Transactions
Example:
Someone send to you 1 BTC paying only 1sat/vB this is Transaction "A", network fee is right now 5 sat/vB, But you need to pay Something to someone else you need to make a new Transaction "B" you need to pay some high Fee, but if you pay the current fee 5 sat/vB, but since the Parent Transaction is not mined yet, then you need to pay more than 5 sat/vB because fee of both transaction are add together, in average both transactions fee is like 3sat/vB so you need to increment fee until the average fee of both transactions reach the minimum level to be accepted by a miner.
And so the games begin...
