I've not started what would be called "Cross Country" nav yet - the solo was just an hour bimble from point to point around the local area and back to the field.
I think the instructor was originally planning to do a couple more flights but we got exceptionally good weather on the day I went and had covered most basics (PFL, EFATO, 121.5 Pan, contacting other fields, diversion planning, basic radio nav, experience of an ATC field as we are A/G) so that's why I was sent off solo.
Cross-country stuff is the next item, obviously with the target being the qualifying XC.
Personally I'm not interested in the hours targets ("I did solo by 4 hours ..." etc), but I do think it is useful to have comparisons like you've asked for just to be sure how it's going.
I enjoy learning to fly and the flying lessons. The instructor is very good at keeping it challenging and throwing new stuff in before I get too comfortable (or as he puts it "when you feel you are getting your head above water, I gently put my foot on and push you back down"

). I'm never overloaded though and it means I never feel I'm bored or wasting my time and money.
I'll qualify when I qualify, and although it will certainly get a bit cheaper, in some ways I think I'll miss the lessons. It's all just such good fun being in the air
Good luck with the nav when it comes CDUK
