Space Engineers Survival Guide - UPGRADE MODULES EXPLAINED - s1s01 

Good guide for beginners, though I wanted to note down some peculiarities I found out about the upgrade modules. Especially the upgrade percentages ingame are pretty weird and mostly misleading. Yield is the most intuitive, in my opinion, as it shows you how efficient the refinery works. All yield upgrades on the refinery give 200% Effectiveness, meaning you get double the ingots for your ores. This is at the same ore intake speed, meaning you are also getting twice the ingots per amount of time. That makes it undoubtedly the best option in most cases. The speed upgrade is an additive modifier of 0.5 per port to the base speed. The assembler has a speed of 1, therefore one speed module does in fact increase the speed by 100%. The refinery, however, has a base speed of 1.3, meaning that one full speed module only increases your ore intake speed to 2.3, which is only about 77% more. All 4 speed modules on the refinery actually only increase speed by about 308%. The performance of the power saving module is not really increasing per upgrade. The Power Efficiency percentage is inversely proportional to the power cost. Arguably, the power saving per module can be considered constant at about 33% per module, but it is a multiplicative effect. To clarify, for the 560 kW base power draw of the assembler, the first full module actually saves you 186 kW, the second 124 kW, the third 83 kW and the fourth only 55 kW. All in all, it saves 80% of the production power draw, the assembler therefore only uses 112 kW when active.

Thanks so much for this video. Super helpful. Instant subscribe. Your voice, style, and depth of detail reminds me of a guy named Red Panda, who used to do great Kerbal Space Program instructional videos.

The Power Saved to PCU cost is insane on Power Modules. This insanely helpful before you reach nuclear power on servers. The PCU cost of solar panels and wind generators adds up quickly

Thanks for this clear video

Seeing as you didn't go back to fix it, how far into recording did you notice "Chagne"?

Spanning 2 refineries do the percentages drop?

Can you attach modules on drills?
