Mast Rake?


So hanging a bucket full of water off the main halyard, I get ~20″ of  mast rake from the halyard to the mast. This is measured just above the furled mainsail, about 24″ above the boom.
Seems like a lot to me…What are you folks getting?

Does anybody have any rig tuning numbers or even guidelines? I’m just guessing about the rig tune at this point.

More on mast rake from Mark H. on Epiphany:

Regarding mast rake on the E34, I measured the rake of the mast at a point 70” up from the deck.  This was done to get around the stacked mainsail.  I hung an approximately 2 ib weight from the main halyard and (measuring from the back of the mast) recorded 20” with no backstay tension on and 24” with about 75% of max, backstay tension.  

It was a lot more than I would have guessed just looking at the rig.   

In thinking about this some more, clearly the perceived (and even measured) rake using this methodology would be influenced by the fore-aft trim of the vessel.  As I look at the waterline, it looks fairly level to me.
