Does the stat increase by Choice users count as an automatic "+1", or can further changes be made, allowing up to "+6" boosts.
For example, a Scizor with 252 Atk and Adamant will have 1576 Attack at +6, does the amount go higher to 2364 (1576 x 1.5) supposing that scizor was holding a choice band while boosting, or is the amount of stat increase a choiced item count as a boost itself, and the stat modifiers are then making changes off of the original, "unboosted" stat, offering the capability of allowing the user to get up to "+7" (1773 Attack) as opposed to 2364, in which case the stat modifiers counted the already boosted stats as the "base" stat to which the stat multiplier(s) are then implied?
tl;dr:
If a Scizor holds a Choice Band while using Swords Dance, does the attack cap out at 1773 or 2364, after accounting in Choice Band boost, and supposing +6
