Those mountains can be safely replaced with ocean now, place ice feature, where you replaced those mountains.Excellent question! I think, yes, as there was a ratio of 56 to 200 with the maps the Rescaled Latitude Modmod was made for to now 72 to 200. I haven't thought about this detail, but only @raxo2222 can say for sure...
BTW, the correct numbers for the earth part is 56x124 (standard) and 72x108 (large). The numbers from Raxo which have 2 more rows stem from the 2 rows of mountains that are needed as a frontier to space and should play no role here.
