Question about where to set Pressurtrol cut out

Good morning, happy new year! I have a residential Weil-McLain natural gas single pipe steam boiler. I very much enjoy understanding how everything works and want to make everything work as efficiently as possible. I’m about half way though Dan’s book, We Got Steam heat, A Homeowners guide’.

A previous owner’s contractor has our gas boiler set at a 2.0 differential. .5 on cut in, 1.5 on cutout.

Small, history had some issues with the heat this winter but they all are resolved now, needed gas company to replace the meter and some other part which increased the gas pressure, before it was only 3.8, now it’s 6.5. Also, had to replace the control module on the boiler earlier this season too. Fyi, there’s a new last winter Gorton #2 main pipe vent as well. I have a mix of Gorton and Hoffman 1a adjustable vents throughout the house. The house is 3 floors but cast iron radiators just on 2 of the floors. 3rd floor has a mini split with a heat pump, it’s a finished 3rd floor but no one rarely goes up there so I keep the mini split set at 60 F.

With all that said, the boiler is running good and consistent and even heat throughout the house.

There’s no banging or hissing from the pipes or radiators but everything I’ve read so far in the ‘We got steam heat’ book, I should have my cutout set at 1.0 instead of 1.5. 1.0 will use less fuel and be gentler on the heating system.

What real world differences is there? So if I decrease it to 1.0, what changes should I expect? Longer heat cycles (probably only a few minutes longer)? And maybe even more even heat throughout the house? (I just want to understand more).

here’s a screenshot form beestat, most of my heat cycles are around 28 minutes or so.

thanks in advance!
