A further update.
I returned Network Logger Pro to the MAS for a refund. I have never done that before and with the new 14 day refund law in the UK it was incredibly easy.
I found a rather silly mistake in NLP where the test times were logged incorrectly, you could not export to a CSV and then import into Excel to be manipulated. I have no idea how this could be missed. I contacted the author and he was polite and said he would fix the bug in the next release. The problem is that by this stage I had pretty much had enough of NLP so it was not enough to change my mind.
I have started using test.my and am pleased. It's free, the author is responsive, it's laid out well and you can export your tests. The only burden is having to keep your internet browser running, but that's a small trade off considering the benefits test.my brings to the table.
