widebody back spacing offset confusion

ok so i've read plenty of confusing threads regarding backspacing offsets et - and + and spacers and have seen many pictures of great looking cars and wheels that simply state the wheel sizes with no rim offsets sizes . now im super confused but i believe i moving in the right direction to acquire a set of deep dish wheels with little to no spacers for my 80 sc steel widebody car with sc trailing arms and turbo front and rear fenders.

... i am currently looking to order a set of braid 17x9/11
from what i understand 9s with a +3 and the 11s with a -21 should fit under my 80 wide body conversion ( assuming the conversion was done correctly and it does appear to be done correctly)... from what i understand from the offset chart. The +3 on the 9s and the -21 on the 11s should give me a 5 1/8" offset /backspace on the rims . giving me the option to adjust the stance a little out with up to a 1/4" spacer if needed.
so after reading a lot about offsets and backspacing and looking at offset charts and diagrams i am a little confused . according to the pictures A zero offset on a 9 inch rim splits the rim right down the middle giving a 4.5" in the front and 4.5" in the back .. but if you look at the chart a 0 offset has a 5" backspacing and 4 inch front spacing from center line .. ( what am i missing ???) there appears to be a 1/2 inch variance on all the offsets ..
i would love to hear from someone who is running 9s with an et offset between -3 and +3 and 11s between a -21 and -27 wondering about rubbing, spacers, no spacers and what tires you are using and a picture would be great ..

Thanks in advance
