This must be some new "official" meaning of "quarter" that I had not
previously encountered.
Anyway, even using real calendar quarters, £130 a quarter does not mean
£10 a week. The Gregorian calendar correction only introduces a factor
of 146,097/146,100, so we can safely ignore that and treat the 4-year
leap-year cycle as fixed. Then in one cycle (16 quarters) there are
1,461 days; and so if they want to collect the rent weekly, the actual
amount should be £130×16×7/1,461 = £9 19s 3¾d. In practice it'd be
simpler to collect £10 and give a free day or two at the end of the
quarter by shifting the day of the week when rent was collected.
And simpler yet to collect by the month, the way I expect it here, even
if that does space the payments unevenly.
