You have to take into account spring sag, rim irregularities etc.
A man after my own heart, I've have not had a good alignment in ages, so I took to the wax string method also,
but I projected each wheel steering angle forward about 10 feet
How was you wear pattern before? I found after 3 years I couldn't get my yaris to steer well regardless of alignment
so either LCA bushings went mushy or cracked or the struts went.
You wont don't know how the wheels will align and run dynamically with normal bushing play, so the initial alignment is just a start.
Then you read the tires each week for feathering, and go by how it steers with each adjustment.
Is it squirrely now with that much toe out? 0.13" is too much toe out.
It should be more stable with a tiny bit of toe in, but you will likely see outer edge tire wear
due to crown counter steer. Do you drive on even moderately crowned roads?
Can you even adjust camber?
I dont recall if there is an eccentric bolt on the strut tube clamp.
I wouldn't worry about measuring camber, you can eyeball that. Basically +/- 0.5deg on most any FWD car up front.
I recall there rear was a twist beam axle. so nothing to be done there.
Was there an initial concern? Or just diving into it for new rubber or ??
Remember tire inflation had to be in a sweet spot also.
