I double-search less than 10% of my queries. I’ve been using ddg for the last four years. I think people that have to double search very often have been trained by google to use queries that aren’t supported by ddg. Google proper has several value-adds besides the search results. Solving math equations put in the search bar for example. I usually use a dedicated service for things like converting feet to meters instead of typing it into google.
