IMPROVEMENT!.. but not there yet

After some helpful replies, info and advice from you guys today I went ahead with reducing the hammer spring tension. I wound the adjuster all the way out until the face was level with the breach block. Result as per below.

What should I do next as shot count still not as high as I expected (60 fish total). Should I increase the firing valve spring tension slightly and should this then reduce air usage / increase shot count? Or.. do I start looking for a shorter than standard hammer spring? OR... is it 'suck it and see'

I'm also a little worried about power spikes especially when you look at those recordd at 110 bar and below. What is this telling me? power creeps up the closer the internal air pressure is to the regulator pressure setting?

All comments / advice will be gratefully received.

PS.

Sorry for the jumbled up data. There doesn't seem to be a way of importing / inserting a table.
