Scrap Upgrades (Scrap Clicker 2)

This is about the Scrap Upgrades from Scrap Clicker 2.

With Scrap
* Value for n is as below:

Faster Barrels
Faster Barrels, not to be confused with the Ad Event Faster Barrels, is often referred as the second best normal scrap upgrade in SC2. It increases the speed of barrel spawning, being important for the Ad Event with the same name and so very important for progress too.

Better Barrels
Better Barrels is theoretically the best Scrap Upgrade. It increases the tier of the Barrels which spawn: Very important for Golden Scrap farming and Scrapyard upgrading!

More Magnets
More Magnets increases the amount of magnets which are awarded when two barrels are merged by 0.1% (17.5% if on max. level). This can be increased with a Tree Upgrade to 0.5% (87.5% if on max. level). Good to get some extra magnets in the beginning, but useless in the very late game.

Doubled Barrel
Doubled Barrel increases the chance of two barrels appearing at once to up to 50%. Very important for the Ad Event Faster Barrels and even for normal playing, like Auto Merger.

Better Barrels II
Better Barrels II is the worst scrap upgrade, it increases the chance that barrels appear a tier higher by 1% for each level - Max.: 75%. This is almost nothing (Better Barrels 1 does same but with a 100% chance and with only one level instead of 75), also it makes speed merging impossible. Luckily a tree upgrade increases the level and so the chance to 100%, but it's still useless.

Better Storms
Better Storms is very important at the beginning, less in the late game. Before x30 it always should be upgraded to the max. which is possible before a storm to get as many magnets as possible. After x30 it should be at 0 or 50 all the time (This is the point where enough scrap is earned fast to max this upgrade). Some leave it at 0 because of storms having a duration of some seconds = less merges while speed merging, but since different storm types got added in 6.0 with the Tires and Tire Upgrades, unlocked at x135 stars, it's worth it upgrading it to 50.

Offline Production
This upgrade increases the scrap gained by offline production. It's pretty good, but the focus should be on other upgrades like Faster Barrels and Better Barrels. It's suggested to upgrade it to the possible max. with the current scrap before leaving the game for 4 hours or longer.
