Will Telekinesis cause multi-hit moves to always hit 5 times?

Question

Telekinesis Effects

Telekinesis raises the target into the air for three turns, guaranteeing that all attacks against the target (except OHKO moves) will hit, regardless of Accuracy or Evasion.

The target gains the usual benefits of being ‘raised’, e.g. immunity to Ground-type moves. More details, including when Telekinesis can't be used, are in the glossary.

The effect is cancelled if the raised Pokemon is hit by Smack Down

Answer 1

You've misunderstood. Rock Blast has a 90% chance to hit, and if it does, then every hit will land, and the number of times it lands a blow is decided seperately, so Telekinesis will not affect this, but it will assure that Rock Blast will hit 100%.
So for example if Rock Blast hits 3 times, each hit has a 100% chance of hitting.

Here are the chances for the number of times Rock Blast will hit:

There is now a 33.3% chance that it will hit 2 times, a 33.3% chance it will hit 3 times, a 16.7% chance it will hit 4 times, and a 16.7% chance it will hit 5 times. Ignoring the possibility of missing, it will hit 3.168 times on average, giving it an average power of 79.2.
