We haven't traded out master suite yet and we've owned since 2001. We have traded the studio and have done reasonably getting 1 and sometimes 2 bedroom units for it but, we've almost always exchanged into Branson, MO which is one of those overdeveloped places in timesharing.
One thing to consider, Marriott is building a brand new resort within 1 mile, Oceana Palms. Oceana Palms doesn't have a silver season, only gold and platinum. Most of OP's silver season falls into the gold season of Oceana Palms but I think I remember seeing were a couple fall into Oceana Palms platinum season. Personally, I think Marriott made a mistake even making a silver season at Ocean Pointe and it seems the agree with me.
I'd still keep in mind that, for internal trades, even if silver season really is better than what silver season should be, Marriott will still probably give it that silver season weight for exchange purposes. However when exchanging outside Marriott, Interval won't care how Marriott ranks the unit.
