I can't accurately say how much, as that is dependent on each individual bike.
ie; Depends on amount of drop, and size of tire.
That is why I bent mine on the bike.
(I heated the stand [slightly red] and used the bikes weight to bend the stand to the appropriate angle).
NOTE: On my bike photo's are not possible.
I (later) added a C-14 rear shock, re-raised the bike, and re-straightened the stand.
On your bike, I would bend the stand about 1 1/2" below the spring perch. (close to the "Y" foot push brace)
My guess is about 10*.
NOTE: After bending, the foot will "not" set parallel to the ground. {I didn't worry about it}
If this is a concern, you can heat just above the foot, and bend the tip "down" so that it sets parallel to the ground.
(Basically bend a "S" or dog leg in the stand)...
All this sounds difficult, but is very EZ to do, and {if you bend too much}, the bend can be corrected.
NOTE: I let the stand air cool after heating.
Ride safe, Ted
PS: As you have a spare, and the original is still on the bike; I would heat/bend the original.
Last thought; Be aware that you could have gas present. As well as plastic and electrical part's are below the bike.
So, direct the heat away from the bike.
I also used a wet rag to cover/protect what I could and had a fire extinguisher available.
