Would you use a regular arrowhead for all of these? The entire text uses these dark arrows. The entire first number line appears to be bold, so I am using the 77 on the whole line.

Bold line from left arrowhead to the empty dot3. Bold line starts at the solid dot and goes to the right arrowhead A bold arrow head generally has meaning. Because all of the arrowheads, including those at the end of a not-bold line, look the same, I would not use the double arrowhead (bold) on any of them.
