Dear Brij (in private)
Thank you for letting me know. The important issue for me that I wanted to share with the list, was not when the leap days occur, but whether the leap day belongs to a 'decaday' or is a blank day. I think it is a blank day, else the double-years would not begin on the same day (Sunday) of the 'decaday'. This is an important issue and is related to the issue on the calendar list about the 5 or 6 epagomenal days being blank days.
I've become curious about the Kali year numbers. They appear to be half the Kali Yuga year numbers (from early 3102 BC = -3101 CE), so could number the double-years. I reckon the Kali Yuga year number for most of 1974 to be 5076. Half of this is 2538 rather than 2544.
Also I'm curious about why you started the double-year on December 23. Perhaps, it has something to do with the December solstice.
If the double-years were based on Kali Yuga, they would begin about a month later on January 24 if Gregorian leap days were used, but about a day or two earlier if 128-year cycle leap days were used.
Note that the February 18 date is in the proleptic Julian calendar, which in 3102 BC was 25 days ahead of the proleptic Gregorian calendar. Proleptic means that the calendar was not yet in use at the time.
I took the liberty of doing some calculations for the Kali Yuga era:
If we start double-year 1 at this epoch, then double-year 2537 (2536 double-years later) would begin on February 18, 1971 - 39 = January 10, 1971 in the Julian calendar, which is January 23, 1971 in the Gregorian calendar. The 39 comes from 2536/64 = 39.625.
Double-year 2537 has no leap day, because its number is odd, but 1972 does have a leap day, so double-year 2538 would begin on January 22, 1973. The new double-years would then alternate between January 23 & January 22 till this double-year, which is 2560 (began on January 22, 2017). This double-year drops a leap day because 2560 = 64*40. So next double year (2561) would begin on January 22, 2019 and they would then subsequently alternate between 21 & 22 January for the rest of this century.

SAD. This slip had not been pointed for correction; and I presumed that it shall be automatically assumed to follow ‘Gregorian Leap Accounting’, and my concentration remained on its “Format”.

I think every year begins with a Sunday of his 'decaday' and so the leap day does not belong to any 'decaday' and so interrupts the 10-day 'decaday' cycle.

It was the FORMAT I pointed, wherefrom I started my tryst - currently it can be in continuation after the death of French Republican Calendar, to last for a mere 13-years.
