My recorder it is not only a simple record position … I tell you i cannot use Slew system for replay (old way to do this things) . I cannot enter in detailed implementation obviously but there are complex algo to achive a good results .
After the first v4.5 release (the first compatible with MSFS) i ll open a discussion for new v5 version (scheduled next version is 2021) I ll add also other features like “raw input replay”)
