For agentic development upwards of 90% is pretty normal! For example, if you make Claude Code explore a codebase, write a plan based on it and your requirements, do a few iterations of further specifying and altering it, and afterwards let it work for let's say 2-4 hours. Sub-agents and dynamic workflows do alter the numbers a bit, but not to a crazy degree in the long run.
