Default How to decipher gwnum.txt lines?

Probably a silly question, but what do all the values in gwnum.txt mean?

I noticed that each line in gwnum.txt corresponds to a set of data from the benchmarks. For example:

Code:
BenchData=3200K,8,8,1,03004470,2021-10-03,12,272.13
seems to have come from

Code:
FFTlen=3200K, Type=3, Arch=4, Pass1=1280, Pass2=2560, clm=1 (8 cores, 8 workers): 29.35, 29.52, 29.28, 29.37, 29.30, 29.25, 29.38, 29.75 ms.  Throughput: 272.13 iter/sec.
So the general format seems to be:

Code:
BenchData=FFT size,cores,workers,A,B,date,C,throughput
But what exactly do the values A = 1, B = 03004470 and C = 12 mean?

I know it's probably not important to the user, but I'm still curious as to what they are for.

From the source module gwbench.c for prime95 v30.7b9:
Code:
/* Create the table to hold the bench data */

    errcode = sqlite3_exec (BENCH_DB,
                "CREATE TABLE bench_data (fftlen INT, num_cores INT, num_workers INT, num_hyperthreads INT, \
                              impl INT, bench_date DATE, bench_length INT, throughput REAL)",
                NULL, NULL, NULL);
...
Code:
/* Read the existing throughput benchmark data.  Format for benchmark data is: */
/*    BenchData=fftlen,num_cores,num_workers,num_hyperthreads,impl_id,date,bench_length_in_seconds,throughput */
...
Code:
        sscanf (bench_data, "%d%c,%d,%d,%d,%08X,%10s,%d,%lf",
            &fftlen, &fftlen_multiplier, &num_cores, &num_workers, &num_hyperthreads,
            &impl_id, bench_date, &bench_length, &throughput);

Thanks. I re-implemented gwbench_implementation_id() in Python for fun and got the same values.
