Best practice
When using "largely based on", ensure the subject's primary influence or foundation is clear to avoid ambiguity. For example, instead of "The decision was largely based on data", specify "The decision was largely based on market research data".
Common error
Avoid using "largely based on" when the subject has multiple significant influences or bases. If a decision is influenced equally by several factors, it's more accurate to state that it's "influenced by" or "a combination of" rather than implying a single dominant base.
