I see it like this. Double time allows you to move up to double your unmodified speed value. And that once you modified the speed value, (Since the value is never replaced) then double time would not work. So yeah you are correct, I do see it as a +1 to the printed speed value.

But you are right in that this cannot be settled without finding the RA's ruling. I can see your side of the arguement and where you are coming from, I just don't agree. I'll try to see what I can dig up.

This is just one of those threads I stumbled into, not a question that came up for me, so I got into it out of mild curiosity. Most times there's a revelatory moment, when I finally realize that I'd been making a false presumption that was keeping me from what should be the obvious interpretation. I know that Quebbster doesn't jump in with arbitrary rulings, hence my continuing to turn this around and around in the light, hoping it would suddenly come clear for me.

The interpretation you're taking would be fine, I'm just looking for something more solid to lean on if it's there to be found. The more solid the basis the better it is for everyone.

I think the point is that Doubletime has NO affect on Speed Values. It simply uses speed value(unmodified) to determine a game effect. If intended as a modifier or replacement value it would be worded differently. Like "Double this characters unmodified speed value" or "The characters speed value becomes..."

If instead of "...it may move up to double it's unmodified speed value", the card read "..it may move anywhere within 3 spaces of any friendly figure" there would be no confusion.

Don't let the fact that the Speed Value is used to determine an effect confuse you.

I was fairly certain that Doubletime was ruled to be a replacement value, specifically in reference to something that prevented replacement values... Isolation, perhaps?

And "Replace then modify" would seem to apply, unless Swingline is one of those "constant modifiers" (like ICWO?) that would try to apply before the replacement value (which means it would be overriden by Doubletime, since Doubletime only looks at the unmodified value).

Thanks, that will give me another avenue to search for the official ruling. I could really care less if I'm wrong, I just want to read it in black and white.

I would consider it an "in-place modifier". Swingline doesn't give you the +1 speed just when you make an action, it's pretty much always there.

You could turn off the feat in order to lose the +1, but then you couldn't get it back again after using Double Time.

The combo is still worthwhile - ignoring hindering terrain for a grounded figure is better than a measly +1 speed.

Okay, the Judges Forum (specifically nbperp) has spoken:

Thanks Burleigh2, I hope that this made the list for at least a FAQ entry.

Good to know.
I also realized that my reasoning doesn't quite apply in at least one scenario: If a figure with Double Time starts in hindering terrain, my reasoning would still let them move double their normal movement - that would just be wrong.
In other words, I'm perfectly happy with the ruling.
