Questions regarding multiple purchased packages, gifting, and upgrades.

Recently I purchased two (2) $30 Early Access Supporter Packs, and I am hoping someone can clear up some confusion I'm having. Here are my questions:

1) If I'm understanding this correctly, purchasing a supporter pack once gets me an Early Access beta (no key will be shown to me on my account page, my account is simply flagged for access). Is that correct?

2) Purchasing the exact same supporter pack again gets me an extra key, and this key is shown to me on my account page, and I can give that specific key away to a friend. Is that correct?

3) If I am able to give that key to a friend, does that friend have the option of later upgrading the package associated with that key through the website? Or must I, as the original purchaser, pay to upgrade that package to a higher tier for them?

4) Assuming my friend is able to upgrade their gifted key to a higher tier package through the website, do they (as normal) only pay the difference between the two packages (i.e. will they pay only $30 to move from the $30 Early Access Supporter Pack to the $60 Lord of Ogham Supporter pack)?

My apologies for the multiple questions, but I'm really trying to get a grasp on how this works before I accidentally make a mess of things for myself and my friend. Any answers anyone can provide would be extremely helpful.

Thank you!

1) yes

2) yes the key will say Used:false and the steam and epic keys are for you

3) Now im not sure but im assuming no they cant and no you cant (maybe if you gift it through steam or contact support maybe)

4) Again not sure but since you bought and they didnt getting the $60 pack for $30 i doubt it

anyways maybe someone else has more or better info or maybe support has better answers
