You should ask a new question: you want some extremely specific and rigorously-evaluated strategies, rather than the existing question's request for "help me lose less." The existence of a give-me-some-good-tips question does not mean that a give-me-an-objectively-best-strategy question is a duplicate. The title of the new question should focus on how precise you want things to be, something along the lines of "What specific strategy has the highest win-rate in Uno?" The question body should highlight exactly the points you're mentioning here: you want the strategy to be objectively evaluated, not just "I lost less often doing this." Unfortunately, since we're (largely) not programmers here, you probably won't get many bites.
