So, a possible character at sixth level has:
+6 / +1 base attack
w/ TWF Feat and ITWF Feat (other "To Hit" bonuses might apply)
First, primary attack at +4 (regular base attack)
Second, offhand attack at +4 (regular base attack with TWF)
Third, primary attack at -1 (regular base attack at 6th level)
Fourth, offhand attack at -1 (regular base attack at 6th level with TWF)
Fifth, offhand attack -6 (regular base attack with TWF, -5 with ITWF)
Other factors will change the bonus, accordingly, but factoring just the pure base attack and bonus from TWF/ITWF.
So, at 6th level, is a character capable of FIVE attacks in one Full-Round Attack Action?
Close... it is a total of 4 attacks at this rate. You would get your two regular attacks for your level, one regular off-hand attack (modified by two weapon fighting), and one more off-hand attack due to improved two weapon fighting.
If I am reading your 5 attack example correctly, I think you are trying to take an off-hand attack for each of your regular attacks, and then another for improved. Two weapon fighting states you get one extra attack PER ROUND, not per regular attack.
Also, note that two weapon fighting doesn't give you the ability to make an off-hand attack, it merely makes it easier to do. Every character is entitled to attempt an off-hand attack; it is just difficult to manage without the feats. Improved two weapon fighting grants you the extra attack that is not possible without the feats.
