("Insincerely" is not the best word here since that carries a meaning "morally wrong".

All I need is clear definitions and terms for various levels of strategic behaviour. A generally used term for the starting point is "sincere opinion". That refers to the independent internal preferences of the voters. After that there are different levels of strategic/optimized/... behaviour. 1) Sincere opinion 2) Sincere opinion modified as requested (e.g. normalize ratings to full scale so that all voters will have roughly the same weight) 3) Optimize vote as requested (e.g. place the approval cutoff between some of the front runners) 4) Optimize vote as well as possible but within generally accepted limits (e.g. exaggerate in Range as much as you can) 5) Optimize vote beyond generally accepted limits (e.g. try to bury in Condorcet) 6) Optimize results beyond what is allowed (e.g. vote twice) I'm quite used to use term "strategic" to refer to all technical changes in the vote that make the vote different to one's sincere opinion. Term "sincere" is often used to refer (technically) to the "sincere opinion" or resulting "sincere vote". Any terms are ok as long as there is a common understanding of their meaning. Neutral and descriptive terms are better than confusing ones and ones with hidden meanings (or ones that are planned to present some particular viewpoint in better or worse light than others).
