I think that in breaking it down further you could look at "...moving your speed,..." . Then realizing your speed is up 20 feet when you tumble it make sense that you could tumble durring the movement portion.
No, that is not quite right. You can Tumble up to 20 as part of your normal move. Tumbling does not reduce or increase your move. Just that up to 20' of it can be tumbling.
from the FAQ
Q: The description for the Tumble skill says you can tumble
up to 20 feet as part of normal movement to move through
an area occupied by an enemy (DC 25), or through an area
threatened by an enemy (DC 15). Does the 20 feet have to
be continuous? If your enemies are staggered apart and you
have enough movement to go through or past all of them,
can you break the 20 feet up into 5-foot chunks to get past
each enemy? Or is this not allowed because it counts as
multiple uses of the Tumble skill? If it is allowed, do you
have to make a separate roll for each enemy you try to
pass? What if you tumble as part of a Spring Attack?
A: Tumbling is part of movement, not a separate action. You can tumble any number of times during a move action, so long as you do not tumble more than 20 feet or move farther than your speed. Each time you tumble, you make a separate Tumble check, using whatever DC is applicable at the time. If you tumble during a double move, you're allowed 20 feet of tumbling as part of each move action.
If you're using the Spring Attack feat, you're taking a move
action and the attack action, so you're moving once and can tumble a maximum of 20 feet as part of that single move. You
could, however, tumble both before and after the attack.
.....
So more specifically it does say that tumbling is part of movement, not a separate action. Which leads credance to the you can tumble AND total defense argument.
Counter arguments to that?
