Doug, look at the diagram.
On the right hand side between 0 and 103 degrees you get p-waves. ... it is written in purple.
Between 142 degrees and 180 degrees you get refracted p-waves. You don't get any p-waves in the shadow zone. Its not possible. No p-wave can enter that area ... not a p-wave, not a pp-wave, no type of primary wave can enter.
Look, here is a wiki page telling you ...
https://en.wikipedia.org/wiki/P-wave#P-wave_shadow_zoneno p-waves ... shadow zone ... why am i not seeing the shadow zone in the graph. If you can't understand why p-waves have a shadow zone, there is no point in trying to work out why the graph might be reporting them despite their not being there.
As a result, there is a P-wave "shadow zone" between 103° and 142°[5] from the earthquake's focus, where the initial P-waves are not registered on seismometers.
Not registered on seismometers. So, I want to see on the graph primary wave readings from 0-103 and some kind of p-waves from 142-180 degrees. I don't want any from 103-142. But that's not what I am seeing. Why Doug? Why? And if you don't know, let someone else have a go. Don't just keep saying I shouldn't have a shadow zone ... I should.
