There are times that it's okay like if you do not want fast confirmations or the average mempool size is low,
but not right now if your transaction is a bit rush.
Refer to the post above for the alternative but I'd suggest to use the 3rd graph instead and look for the range that suits your transaction best.
Eg: Using that site, fee rate at range of <1MB has a good chance to get confirmed in the next block, >1mb for the next and so forth.
Note that the number of newly broadcast transactions and rate of mined blocks can increase/decrease that chance.
That's when your node isn't synced or you're not relaying unconfirmed transactions.
