Arrowhead double stroke appearance bug

[Franck Payen]

I know beautiful strokes is now a more than a decade far away (CS5), but I'm a heavy user of appearance panel, and sometimes I get annoying reproducible visual bugs (at this stage this is no feature request).

On the left, my bottom white stroke has a 4pt width, when the top black stroke has a 2pt width.

The arrowhead being a fill, it is of course not treated alike, so I thought "Oh, may be, making a 50% arrowhead might be a solution ?".
Well, not so much.

And YES, putting the arrowhead's point at the end of the stroke doesn't fix it, it's even worse :

I even did a measurement of the weird values I had :

And just in case you wonder…

Does this work for you; a duplicate stroke with outline stroke and offset path in the Appearance panel?

[Franck Payen]

Yes it does thanks. That was also a suggestion from @Egor Chistyakov i followed. Thank you both.
