Skill Points > Perk Points > Influence Points > Rank

FH4 has several scoring systems that make it a bit confusing for me. Maybe you can clarify it for me with my questions below.

Skill Points

I believe that I understand this:
100,000 skill points = 1 car perk point
500,000 skill points = 10 car perk points (max for any skill chain performed)

When skill point farming, I will get ranked up in “Global Influence” and “Skills Influence”.

How many skill points does it take to rank up in “Global Influence” and “Skills Influence”?

Perk Points

I understand that the first car perk has an influence value that claims to be immediate. But there are also some other car perks that include influence points but I am not exactly sure when those points get applied to my score or rank. Can you clarify?

When in the garage applying perks to the cars, I will get ranked up and see that I did when leaving the House.

How many car perk points applied and type does it take to rank up?

Thanks for the responses.

50K Skill Score = 1 Skill Point. That’s why 500K Skill Score = 10 Skill points. You buy perks with these points.

Influence (called experience points or XP in a lot of games) is just how you level up in general. Influence can be earned in many categories, including skill, all of which you can see in the Horizon Life screen in the main menu. Global Influence is just the total of all Influence earned and gives you you overall driver level.
