Just remember where everything goes and put what you have in the right place - don't know if it works for wind up because I have never used it that way.
Start with the wind if you have it - wind direction at the top, wind speed below the center dot and mark with a cross or other indication.
TAS under the center dot, heading at the top (where it says "True Heading"!). You now have your drift & GS under the wind cross and can read track off under the same drift angle at the top of the computer.
Of course you often do not have the heading to put at the top in which case you put a guestimated or approximate heading at the top (many people start with their track) and just keep adjusting it until the drift at the top (under your track), and that under the wind arrow, match.
If you learn it like this and just put in the elements you have, you can solve almost any wizz wheel problem that has 4 elements given.
