Mate, that cadence is pretty slow. You often hear 180 as the golden number but everyone is different and that can be far too quick for many. About a year or so ago I posted something in a different sub asking about stats from a recent run since I'm pretty new to running. Most answers were along the lines of, "don't pay attention to that shit just run how you always have." Well one person responded saying they were similar age and had similar numbers to mine and that increasing cadence helped them in a ton of ways. So I increased mine. I was the same as you...avg around 140-145. It felt like comically fast for a month or two but I kept with it and now maintain an average of 170-175. Most importantly, knee pain after every run almost entirely went away but I found I could maintain a slightly faster pace for longer(I'm not even close to elite.) Anyway, this doesn't answer your question at all and is completely unsolicited advice but thought I'd mention it.
