A reference over 16,384 cells was cut to the sheet's used range when it was
read into an array. Next to a full-size operand the two no longer lined up:
SUMPRODUCT(D3:AZ400*B3:B400,(A3:A400=1)*(D1:AZ1=2)) gave #VALUE!,
D3:AZ400*B3:B400 filled with #N/A, and ROWS, COUNTBLANK and --(r="") lost
the blanks past the data. Excel keeps the reference's size.
Bounded references now keep their full shape up to one column's worth of
cells (1,048,576). References that run to the edge of the sheet (A:A,
A2:A1048576, several whole rows) and larger blocks still stop at the used
range, so whole-column formulas stay fast.

AAA exponential smoothing (Hyndman et al. 2008, ETS(A,A,A)) over an evenly
spaced timeline: documented seasonality, data completion and aggregation
arguments, calendar-month date timelines, autocorrelation seasonality
detection, state-space prediction intervals, statistic types 1-8.
Smoothing parameters minimise the in-sample SSE (grid + clamped
Nelder-Mead). XLSX export treats the family's range arguments as
array-taking (no spurious dynamic-array metadata), FORECAST/FORECAST.LINEAR
included.
