This is completely upto you. Applicants may use one, two or three anecdotes to illustrate their spike factor. Nothing is hard n fast. If your one anecdote is lengthy and rich enough to strongly illustrate the spike factor of your choice then one is enough. It’s completely your choice. Depends on your story. People usually use more than one.

Is it a mandate/preferred practice to write only 3 stories/anecdotes in the spike factor essay?
Is the upload still an issue? Do you see any file size limit on the upload page ?

It redirects me to a page that says ’Invalid’ when I try to preview my photos. I am not getting any option to re-upload either!
