Thanks for your kind words, but it seems your map has taken-off way more than mine.
As discussed before, it's quite a crude approach, but I guess it's better than nothing...
So rather than duplicate efforts I've changed the original map from public to unlisted (doesn't seem to be possible to delete the map entirely).
*update*
I think it is possible, pretty sure the original map's now deleted entirely, sorry to those who added themselves.
