A central part of experimentation in scientific fields is to document the experiments in a very comprehensive way, including - which other options you also tried, but which failed - write down hypotheses that explain the worse results of the other options - write down hypotheses why the chosen options gives better results - ideally formulate testable predictions that these hypotheses imply - etc. Simply saying "other alternatives were tried and those happened to work" is not science, but tinkering around combined with magical thinking.
