When deciding between options B and C, it's important to consider more than just the percentage improvement over the baseline. Other factors to consider include the costs and resources required to implement each option, the potential impact on user experience or other metrics beyond the primary one being tested, and the overall strategic goals of the company. For example, if option C requires significantly more resources or has a negative impact on user experience, it may not be worth pursuing even if it has a slightly better performance than option B. On the other hand, if option B aligns more closely with the company's strategic goals, it may be the better choice even if option C has slightly better performance. Ultimately, the decision should be based on a holistic evaluation of the options, taking into account all relevant factors and weighing the trade-offs between them.
