Another close figure: The sidereal day is 3 minutes, 56 seconds shorter than the solar day. If the solar day has a negative leap second, the difference is 3'55".

I do not know what some terms mean, but I think that is not another close figure, that is the same figure.

I mean, close to 3'54".

If the sidereal day and the solar day mean what I am guessing they mean, your 3:55 and Lumifer's 3:55 come from the same place.

No, what he did was divide the sidereal day by 366,24 and got 235 seconds, so there would be as many Stone's periods in a day as there are days in a year.

Yes, and my claim is that that is what you did too without knowing it. Think about what sidereal and solar day mean, and how you would calculate one from the other.
