Die visuellen Verbesserungen, die ich in VADER-DEB hinzugefügt habe, helfen, mehr Einblicke in die
Das ist also Dual VADER w/Energy Bars
Diese Änderungen mögen von manchen als klein angesehen werden, aber meiner Meinung nach fanden ich sie visuell ansprechender und besser für
Die Kernberechnung im Code ändert sich nicht, wie die obige Grafik zeigt, in der wir beide VADER-Versionen nebeneinander vergleichen.
Wenn Sie mit der VADER-Version 3.0 zufrieden sind, können Sie sie weiterhin verwenden.
Viel Glück!
