I always benchmark at a baseline of all third party apps terminated. No background Dropbox, MagicPrefs, Paste, Bartender, Droplr, 1Password Mini or other utilities. This is usually what professional testers do to be consistent and establish a baseline for comparison. I also wait at least a day on a new machine so Spotlight can stop indexing, iCloud Photos can sync, Time machine can backup, etc. I also unplug drives and external displays. I benchmark after a reboot and wait about 5-10 minutes for everything to settle down. Might explain why mine is faster, but it’s also not a fake result even though you’d be running these apps while working because it removes variables between user configurations when testing. Many people don’t think about this and could be running tests with all kinds of things going on in the background and who knows, maybe even half the Adobe Creative Cloud running, lol. I also check activity monitor before testing to make sure nothing weird is going on and that the CPU is close to 0%. I’d say my results are more likely to be consistent with professional benchmark results.
Yes I had Steam running in the background for instance last time. Will try it with everything else closed down to get more accurate numbers.
