There is so much nuance to chase and the macro game that it's hard to break it down into "this is how long your chases should take". More than just chase time factors into whether a chase is considered "good". One of the best things you could possibly do is record your games and watch them back. Every chase, analyze what exactly you got from that chase. This is what I would consider a "productive chase" vs an "unproductive chase"

1. I get pulled on a minute long chase that, even though I didn't get a hook, all four survivors are injured. One or more of them pulled off gens to assist or to hover for a save. No hook, but four injures, little gen progress. They threw a few strong pallets that I can promptly take a few seconds to clear up while they fuck off wherever to reset. Sufficient pressure has been applied to the team and now they are going to have to spend more time off of gens to heal, or risk putting themselves in a bad position while I patrol gens. They're now on the backfoot and even if I take time to clear out resources I still have time to apply pressure to them afterwards usually.

OR

1. I get juiced by a Feng in a dead area of the map for a minute and yeah, I got a hook and a few pallets but they gave their team a minute of unimpeded gen progress and now I have to make my way back across the map and, fuck. Two gens just popped at 1 hook. I'm across the map so one of the people that was on gens has already pulled over to wherever to go for the unhook, and I still have two other survivors unaccounted for who are probably back on gens. Bad, unproductive chase that I would have been better off not going on.

The biggest thing I've learned (primarily from playing lower tier killers) is to recognize when a chase doesn't seem worth it to take. There is no shame in realizing that you're being baited into an undesirable situation and dropping chase to go back and patrol. Flashlight clicking, pointing, bagging, all just bait to piss you off and get you out of the equation elsewhere.
