It's something of a miracle that we ended up with 625 for all 50Hz countries. With 2 exceptions. One was the legacy of 405, the other was the bold but ultimately failed push to HD with 819. Like all standards, 625 was a compromise but time showed that it was a good one.
Yes it was lucky the amount of lines were standardised, but I did wonder why we ended up with 3 different sound seperations, especially the Irish & UK choosing 6 MHz when almost the rest of western Europe standardised went for 5.5 MHz.
