train to spamassassin in PMG worth it or not?

[mazaamahesh]

I am training to PMG spamassassin from last few month following is my dump magic output

0.000 0 3 0 non-token data: bayes db version
0.000 0 7640945 0 non-token data: nspam
0.000 0 109340 0 non-token data: nham
0.000 0 143865 0 non-token data: ntokens
0.000 0 1745031293 0 non-token data: oldest atime
0.000 0 1746445765 0 non-token data: newest atime
0.000 0 1746445860 0 non-token data: last journal sync atime
0.000 0 1746401177 0 non-token data: last expiry atime
0.000 0 1382400 0 non-token data: last expire atime delta
0.000 0 10808 0 non-token data: last expire reduction count

still some spam emails not blocked by spamassassin does it worth it spending this much of time on it?
