Your thinking on increasing the termination period is spot on. That was inserted primarily to cover the case where the Startup terminates the agreement after the Mentor delivers but before a 'fair' amount of vesting has happened. An extreme case would be where the Mentor delivers significant value before the Cliff Period ends, but the Startup terminates the agreement before any shares have vested.
Mentor/Startup alignment is key.

We intended to launch the Mentor Shares site so you could both view the page and download the documents without registering, but the open download bit obviously didn't stick.
We've updated the page now and you can download the docs freely.
Having f6s generate a doc for you still requires log-in.
