There is some information on this at:
https://c14.arch.ox.ac.uk/oxcalhelp/hlp_analysis_oper.html#deposit
I think the best method probably is:
Sequence()
{
Boundary("Start");
Interval(N(10,5));
R_Date("A",2023,20);
Interval(N(10,5));
R_Date("B",1961,20);
Interval(N(10,5));
R_Date("C",1999,20);
Interval(N(10,5));
R_Date("D",1966,20);
Interval(N(10,5));
R_Date("E",1954,20);
Interval(N(10,5));
R_Date("F",1936,20);
Interval(N(10,5));
R_Date("G",1948,20);
Interval(N(10,5));
R_Date("H",1925,20);
Interval(N(10,5));
Boundary("End");
};
The difficulty comes if you have some gaps that are definite and others that are not. Neither this nor V_Sequence will work with zero errors. The error can be set to be 1 year though which works for most things. These methods are more often used for varves etc.
A completely different approach would be to use a P_Sequence with z set to be the cumulative ring count. This might be more suitable for species where ring counts are very variable.
Best wishes
