For something this small, use a single VI to manage it in memory:
It has a FUNCTION input, an enum with values of (INIT, READ FILE,
WRITE FILE, ADD ITEM, FIND ITEM).
It has a CLUSTER input, which is your record type {Item number, serial
number, time stamp, description}
It has a CLUSTER output,
If you right-click on the VI's icon in the top right corner and select
patterns you can select a connector pattern that has more terminals.
The maximum is 28.
If you ever need more than 28 the solution is to use clusters and
arrays.
but there are not 17 terminal in the patterns
You can also adapt it exactly to the number of terminals you need; if
you have 16 and just want one extra just right-click on the pattern
(where you assign terminals) and choose to add a terminal.
You do not need to use them all, just select a pattern that has more
than 17 and wire up the ones you need.

unbundled, but the data doesn't go anywhere.
2) The sub-VI outputs a boolean, but nothing is done with

If all you need to do is to calculate the average of a segment of the
array just wire the array to the array subset function and specify the
start and length of the subset you want. Wire the output to the
average function (or a sum-function and then divide by the length).
If the arrays are very

I added a 2nd indicator just to demonstrate use of a DBL formatted as
