Boots of Striding and Springing on a Monk

[Xeoble]

I thought i knew the answer to this, but after reading the "Am I reading this correctly" thread, i'm not so sure.

Ok, lvl 20 monk. Base speed 90. Boots of Striding and Springing.
What is their speed?

100? Tops out at doubling non-supernatural base speed?

140? Adds non-supernatural base speed to supernatural base speed?

Tops out at 100, double the non-magical speed since all spell-like and supernatural speed increases don't stack. The same is almost always true for skill modifiers as well.
