Monks have "medium" Base Attack Bonus progression (like bards, rogues, clerics), meaning they don't get +1 BAB at 1st level and every 4 levels after (1, 5, 9...). So at level 9 you have BAB of 6, not 8.

What you see, however, is the effect of Flurry of Blows, which gives you extra BAB when centered and using special monk weapons.
