[Elecraft] K2: winding T5

Hi all,

I'm at the point of winding T5 and have a question about whether I have it
wound correctly. In particular, it seems like the step-down winding (the 4
turns of green wire) can't be perfectly centered over the other winding (the
16 turns of red wire). I.e. if you start counting turns on the 16-turn coil
from one side, the first pass through the core of the 4-turn winding occurs
between winding 6 and 7. If you start counting turns from the other side,
the first pass of the 4-turn winding occurs between windings 7 and 8.

Does this sound like it's wound right? I can't see any other way to wind the
xformer without this being the case. It's symmetrical if I turn it over -
i.e. if I flip it, the 4-turn winding is "off" to the other side by 1.

if this is wound right, does it matter which way it's installed? i.e. which
leads are 1/2 and 3/4?

The manual doesn't specify so I'm assuming it doesn't. But this is a little
bit of a Rubik's cube type of puzzle for me I guess ;)

Thanks,
LS
