I would like to hear from people who have either monitoring tools or
bots that rely on the incorrect physics FPS. If these people exist,
let's hear what pain it would cause them to correct the number.
Otherwise, I don't see any reason to continue to report an incorrect
number, and I see many reasons for fixing it: several PhD students have
now either wasted a lot of their time or even made wrong data analysis
because of this.
