Thanks for taking the time to answer guys. Appreciated.
The thing is, from a quartersawn piece, it's pretty difficult to determine the twist the trunk had, right?
At least with my rather untrained eyes.

What is the measurement from heart to bark, and if you lay the piece on a table with 3 corners touching the table (or as near as possible) how far from the table is the 4th corner? Whatever that is, it's the amount of run out that would be at the outer edge of the top plate.
Yep, 60cm is the lenght.
I'm a BeEng Mech so I tend to think eveything in drafting, metalworking and construction terms
I didn't take any precise measurements and didn't do the math, just eyed the pieces, but I'd say that with a 25 cm wide (from heart to bark) 60cm long piece, the 4th corner rides 6-7cm high.
The piece was from about 2.5m height, and I intended to use the lower portions as the trunk isn't excactly huge. Well not huge from instrument making viewpoint, I nearly tipped my Nuffield when carelessly swinging the lowest portion of the log with the ancient Hiab loader
Even the quarters I made with the aid of a chainsaw were a handful.
