The arrow appears to be pointing at a med-high attachment point.
How far up — in relation to your exit point — does your pubic bone end?
To answer your question, it depends again on the definition, how you define the end of the pubic bone.
My pubic bone curves inside the body at the end. Which point do you mean? The highest on the front face or the point behind the highes point which is curved into your stomach (which is actually higher on your body,but more inside the body because it curves)and you have to press into your stomach to feel it. To find this, you press your fingers into your pubic bone coming from above, from the stomach.
Or in other words, if you would push a ruler in there, you would got a higher measurement, because the bone curves inside there, inside the stomach,you would have the ruler at the very low of your stomach, but you hit the pubic bone.
Hope you know what I mean, it’s hard to explain. If you do not got me, I will search for a graphic and do some drawings.
