17%+17%+17%+13%+13%+6.7%+6.7%+6.7%=97.1%

probabilities over 10% are displayed as rounded down

true, but if you take a look at his "starting probabilities":
start_prb=0.177 + start_prb=0.177 + start_prb=0.177 + start_prb=0.133 + start_prb=0.133 + start_prb=0.067 + start_prb=0.067 + start_prb=0.067 = 0.998

so how many decimals do you suggest I should add to make it exactly 1.... 10? 20? 3000000000? 1000000000 million?

i recommend to keep the start_prbs as simple as possible. i wouldn't use start_prbs like 0.177 at all.

eg:

a: 0.22
b: 0.18
c: 0.22
d: 0.12
e: 0.14
f: 0.04
g: 0.04
h: 0.04

Yeah, i would too

so if thats what you wanted to say, why didn't you say so in the first place?

those percentages are rounded of course, internally it's correct.

(Or as correct as it can be representing fractions in decimals)

The text included with the fixture is really confusing... Z4 is going to the WCG for sure without playing, so basically we're looking for the winner of the USA qualifiers? Or is it the second place at the USA qualifiers?

second place at the qualifiers

WHY would you do a second place fixture? especially when there isnt a first place fixture, and "who will take first" is a question which no one is sure of yet.

/me feels the need to remove this

euhm the above 2 already qualified i thought? so remove them? and refund my money :\
