all-time record in database - and yet another bug

Just to provide some more scientific geekdom, here is a shot of the current record of my spectral UV database: 512029 data points! To see what this database is all about, see my previous post, forest behind the trees. After I finally managed to crack the MATLAB code in which I foolishly had decided to save my very first data sets, I was buoyant with joy over that accomplishment and imported everything into my filemaker database, which I use for editing and checking data before it goes on into the MySQL database where it is eventually calculated into outputs and plottable data. But more about that stuff later...

Anyway, I realized that I had broken the barrier, >500.000 data points!

Filemaker-record

Note that every line represents one spectral data point of one measurement, i.e. one "shot" of the spectroradiometer is broken down into 18 UVB channels, 38 UVA channels, and 70 PAR channels. Cool, huh?

Only one question remains: if every time I push "scan" on the instrument's interface, it records one spectrum (250-575nm, of which I use only 280-550nm) which is broken down into 126 channels with a 2.15nm resolution, why the **** does the database now suddenly contain 512029 records?

It does not take MATLAB to figure out that there is something fishy here - again... :-(
