A good way to tell is to go online onto ICO and play some multiplayer. 

Go play some of the pros.

What you will need:

1. Tissue

2. Stop watch

The tissue is for the tears for your first 10-100 losses in a row.

The stop watch is to guage how long it will take for you to get steamrolled.

A higher time per game will indicate progress.

When you can last 1 hour against another player in multiplayer, you will be well on your way of achieving prescience, so you can predict exactly when the developers add the new content.

I hope this helps
