I only found a reference to the number 70 on page 19. I think that relates to the required experience for converting an existing national license (might be a UK PPL or NPPL?) to an EASA PPL. It says it's for non-JAR licenses, too, and earlier in the doc says that JAR PPLs will be converted automatically. So I don't think it's about ab-initio training (if that's the right term).
Interesting bit in section 6.2 (page 9) on the IMCr. It's no guarantee but nice to know that EASA are at least trying to placate us. I'm studying for it now and quite keen to be able to actually use it - legally - for more than a year!
