Less or equal, yes. When "economy" fees <= 1.
is there a possibility that the default result on /fee alert is not an "Economy" fee?
Such notification is often not usable because the economy fee is not enough to complete the transaction, especially lately when the network is overloaded.
For example, I set the alert to 10 sats/vbyte, and very quickly I received a notification that the fee was below that, but it is very far from reality. So if I'm waiting for a certain fee to make a transaction, information about the "hourly fee" status is more useful to me.
