Why make life difficult for yourself.
If you want to check the wind then ask ATC for a wind check and simply adjust the surface wind up to what is will roughly be at the hold level.
With that wind, you can use your head to calculate the single drift for the inbound and thus what you are going to do on the outbound. You can also quickly know the head or tailwind so that you can adjust the timing.
If you sit down and use the wizz wheel to plan headings and timings in the hold prior to departure or even for that matter doany form of notes regarding the hold headings and timings, you really need to try and stop relying on these because some day soon ATC will direct you to a hold you have not planned for and what will you do then?...please refer to the above advice!

PS, remember that even on the IR initial test, the first time round the hold is simply feeling your way....the second (and subsequent? )time(s) should be better
