I'm not sure this actually answers the question itself, but may provide some perspective as to what is involved in humanisation.
The 'trouble' with humanisation, is often the sum of the individual humans making up the final groove - even if it was all actually the same human - in itself varies over time.
The inaccuracies contribute to the eventual feel of the entire piece, though the push-pull between accuracy & 'groove' can change over the piece itself, getting tighter as the performance progresses.
The perfect illustrative example, to my mind, is Stevie Wonder's 'Superstition'
Bear in mind that the instrumentation is just drums, syn-bass, 2 clavinet tracks [all played by Stevie] & 2 brass tracks.
The drums were laid down first, as was his usual working method. I don't know in what order the others were recorded, but you can be pretty certain the brass was last.
Taken as a whole, it has got to rate amongst one of the best groove tracks of all time (I'm sure that bit of opinion would be allowable on SE ;-) yet if you actually analyse what each instrument is doing, it's all a bit of a mess.
For the entire first verse, nothing seems particularly in sync - yes, it's a great riff, but the clavis wander in & out from each other, the drums push & pull a bit, yet not at the same time as the clavis. By the time the brass comes in, they sound like they agreed that "the last one to finish buys the beers", so they're trying to get to the end as quickly as possible.
The brass continues in that vein for the length of the track - but in actual fact, that apparent rushing really ties the groove together & drives it very hard.
The second verse does pretty much the same as the first, yet a little tighter - also your ear starts to get more forgiving to the individual components as your 'heart' really begins to grasp that what is actually happening is really something a bit special.
By the time you've got through the middle 8, you are fully hooked, & even though the clavis are tightening to the drums, the drums themselves are still a bit wandery on occasion, some of the fills leave a bit to be desired... & the brass is still in that race to the finish...
... but by then you no longer care!
The track wins, your analytical brain loses & you are caught up in the moment.
