I note your initial sequence had 1952 duplicated but you still count
1951-1953 as a sequence of length 3 so I added in a couple of
distinct-values() calls here which might or might not be OK.
This returns 3.
declare variable $s:= ( 1945, 1951, 1952, 1952, 1953, 1961, 1962, 1998);
for $i at $p in distinct-values($s)
$i - $p
for $j in distinct-values($ss)
