That does make sense to some degree, but with the competition being called the beginners league, it seems essential that newbies get to take whatever time they need (provided they can find it) to hone their skills.
Personally I find this back-and-forth of ever improving laptimes quite interesting - I had a 200hp car doing 17.2 around the ATT before FrankNStein asked the question about anyone having 200hp (but I knew it was still a bit rough). I've now got something into the high sixteens which I'll need to look at when I have time, though I'm not sure I would have had much motivation to look further without Newtonmeter's latest milestone.
It was similar in BRC to some degree. You build a thing, post a solid time and think well, I don't think there's much more time left in this. Someone beats it, and you give your thing a critical once over and go "what if..." and then suddenly it's a second faster than the other guy (which prompts them to do the same, and so on).
Though it's hard for newbs to beat the veterans, the milestones should give something to work towards, there is plenty of information in the thread and ultimately some expert-built cars get shared now and then. I don't think anyone new to the game would get this much this quickly out of tussling amongst other newbs without anyone showing what's really possible.
