I think because AP had 15300 produced from 2005(the release of cal 3120) late f series to merely early h series. When 15400 was introduced from 2012, mid h series until 2019 current k series. f series was app from 2001-2005,g was 2006-2010, h was 2011-
And back then, it was all about ROO. So even though 15400 had same production years, 15400 maybe 4 times more produced than 300s. I think 300 will be rarer than 15202 if they keep up their production.
