MF / SO is usually described in the MF cost per 1000 StarOptions, so I really can't tell anything from the numbers you have provided. However, from the latest numbers I have are as follows;
SVV Bella (2018) - $14.43 / 1000 SOs
WKV (2017) - $10.61 / 1000 SOs
WKORVN OF (2019) - $14.95 / 1000 SOs
You obviously want the lowest number to have the lowest ongoing cost. However you also need to consider some other factors if you are looking for an SO generator. Maui doesn't seem to make sense for an SO generator because it has a high MF and high ratio compared to the other two more common properties that are to be considered. I also think your WKORV OFD number is still off since it has the same SOs as N but a much higher MF. Maui also has a very high purchase price which would wipe it off any list as an SO generator. Now, comparing SVV to WKV. SVV platinum 81K weeks sell for $1500-$2000 where WKV 148,100 sells for $15,000+. While SVV does have a considerably higher MF/SO ratio, if you factor in the opportunity cost of the additional $13,000, even at only 3%, WKV is now close to the MF to SO ratio of SVV.
WKV is good for many other reasons, as a renter for example, but IMO it isn't the best SO generator. Leave that to SVV. Now let the flames begin!
