LA Deadeye Freeze build up

I am mostly following Fubgun's guide and notice he sometimes makes various changes. I am taking a more defensive approach maintaining Acrobatics and +71% evasion, I guess up for debate if it's worth in the first place.

His latest changes drop Forces of Nature and Emboldened Avatar in favor of Frazzled. I guess that much Penetration isn't always needed and a higher shock effect would result in more damage.

He either picks up Pressure Points or Thin Ice and Heavy Frost.
I was wondering at my gear level (working towards 150% quiver effect), could I go without either.

I know freeze depends on map mods as well. I avoid monster ailment threshold but was wondering what impact delirious level or extra life would have and would they make map clear much harder without investing in freeze effect.

I've tried testing but really struggling in simulating a decent sample size in similar conditions. I've noticed 65+ deli really makes freeze harder.
Is there like a benchmark of tooltip cold damage for LA/Heralds?
