Reforgelite uses character sheet stats to determine reforging so that's not a worry.
I should of probably said that it's actually updating the numerical rating not just the %. So it's working in character sheet without having to do anything. I.e reforged to a breakpoint with the trinket equipped, and when you unequip the trinket it goes to actual values sub the amplified %.
So from what I can see you just need to use the default breakpoints and hit reforge if you don't use the trinket for a fight and back again when you use it and it will add / remove accordingly.
