Mouse & Aim
Sensitivity conversion, eDPI, cm/360, and polling-rate math so the same sens follows you between games — built around the r/MouseReview and r/CompetitiveApex conversion threads.
Display & Performance
Monitor PPI, refresh-rate frame time, response-time effective Hz, and ultrawide FoV math for the r/Monitors and r/buildapc crowd.
Game Math
DPS, TTK, damage falloff, and headshot breakeven math that finally settles the r/CompetitiveApex, r/Valorant, and r/GlobalOffensive damage debates.
Build & Setup
PSU sizing, CPU/GPU bottleneck quick check, Steam refund window, and a $/hour entertainment value calc — the recurring r/buildapc and r/pcgaming pain points.
Network
Ping-to-reaction, jitter/bufferbloat, and Mbps-needed math that addresses the r/InternetSpeed and r/CompetitiveApex 'is my network good enough' thread.
Streaming
Bitrate, codec, and clip-length math for OBS / Streamlabs setups and the r/Twitch and r/youtubers streaming questions.
