That typo has been in HARP and HARP SF since the beginning and from my review of the forum archives, I can find no trace of anyone ever asking about it....
The spreadsheets that have been created for HARP character creation seem to go with In/SD almost 100% of the time (including the ones I use), however now that you point it out, my recommendation would be that it should be Re/SD. I see the skill as a combination of knowledge and absolute body control (to avoid accidentally poisoning yourself).
