Is there a limit to the number of different entry types a section can have? For this project I might need 50+.

I think I need more content to meet the quality standards so I'll explain: my client wants to create multiple reports for her customers to fill in. My client is comfortable with craft backend and knows how to create fields/sections/etc. I want to keep all the report entries together. Ergo a Reports section with a different entry type for each report.
