        <pre>It looks related to INF. Replacing its reference in LAST_ROW by its expression,
like this:

<span class="quote">> LAST_ROW:  MATCH((2^53-1)*2^(1024-53);$Tickets.$A:$A)</span >

fixes the problem. It turned out that I made a mistake while preparing the
example, moving IFERROR's last argument out of the argument list - that's
unrelated; the correct formula in Billing.A1 / Tickets.D1 is

<span class="quote">> =SUMPRODUCT(IFERROR(CEILING.MATH(DURATIONS;300);0))</span >

and in Billing.A2 / Tickets.D2 is

<span class="quote">> =SUMPRODUCT(IFERROR(CEILING(SUMIFS(DURATIONS;IDS;IDS);300)/COUNTIFS(IDS;IDS);0))</span >

Why could INF cause this? There's no built-in function named so.</pre>
