It's worth clarifying your use of the "p" rating scale alongside the "dan" rating scale. Essentially, there's an "amateur dan" scale which is what's measured on public servers like KGS. Under this scale essentially all professional Go players rank at the maximum rank, 9 dan. In parallel there's the professional ranking system which also uses the title "dan" but is bestowed by the professional Go associations of every country. These rankings are symbolic instead of quantified, although generally higher professional dan ranks cannot be anything but corresponding to higher skill. So, a "European 2d" is a professional rank which may or may not have a good translation into a quantitative scale like ELO or "KGS dan" (I actually don't know). Generally, my understanding is that European professional rankings lag behind Asian ones as well by some amount.
