Oh, not offended - glad it helped! Just saying it has some rough edges.
If you're testing your application in Wokwi, you can create another independent PWM generator to represent your second motor by selecting it, then press "d" to duplicate.
It easy to deal with max rpm as the pulses (interrupts) are quite frequent, but dealing with minimum rpm is a bit more challenging. At some rpm value below 60 or so, you might just want the rpm to display 0 rather than wait for the next interrupt. Also might need a timeout value that will make the rpm display sero if the interrupts occur too slowly or are stopped.
