I’m just showing what I’m doing. I don’t always know if it’s right or wrong but maybe the picture alone will help someone.

Really interesting stuff, thanks for posting. I rented LPB in September 2014 when (presumably) these valve seat recession / low compression issues were already well established, but the car still performed well in the two days I had it, with no obvious misfiring. It pulled strongly and swiftly without any hesitation to 4,000+ rpm in each gear, and also wafted along at under 2,000rpm in top very smoothly. I assume that under actual running conditions, i.e. being fully warmed up, helped to compensate for / reduce compression loss via the damaged valve seats. The only issue I experienced was hot starting (e.g. refuelling after a run), which took up to 20 seconds of cranking. However, period road tests mention this, so I didn't think anything of it at the time. Also, when I rented it, I specifically asked what fuel to use and if an additive was needed. I was told unleaded was fine.
