Passively, you generate 40% of max MP per minute. This meant that, if not overcapping Oath Gauge. If you never used Shelltron, even just to "waste" it for the free MP from OT position, you needed to actively generate 3288 MP, alternating 5 and 6 Riot Blades per minute. If you didn't perpetually overcap your Oath Gauge, however, you needed only actively generate 1368 MP, barely over 2 Riot Blades per minute. The 4 Riot Blade value before was assuming you, for whatever reason, were only able/willing to use Shelltron once per minute.
Things were not tight back then. You could manage off 2.28 Riot Blades per minute, which you did anyways just from maintaining Goring Blade.
