My Question or Issue

Dear Spotify users,
I like to use radio based on my playlists function. However I don't know what is the limit of tracks in playlist that algorithm can read. Somewhere I've read that the algorithm reads first 250 songs of the playlist. But it was a few years ago and maybe something has changed since then?
