The traditional tropic year match to von Mädler
But if the years 3200, 6400, 9600, 12,800, 16,000 and so on are NOT leap years the duration of the mean Gregorian year will then be 365.2421875 days and this approaches very closely the real duration of the mean tropical year which lasts 365.24219 days. So that a very little error of only 3.125 - 3.100 = 0.025 days in 10,000 years will then be made.
