This coordinate chart is based on my personal experience; it is entirely subjective, and results will inevitably vary from person to person. Factors such as ambient temperature and humidity (referring to your general region rather than the immediate, momentary conditions) and the specific mouse skates used will all affect glide speed. I’m not sure why you all asked for this, but here it is. I’ve also included a quick test for the Eira: a 23° incline test, using a 43g mouse equipped with "Lian" skates. The second image shows the results from today’s testing(after about a week of use), while the third image shows the state of the pad when it first arrived. It’s worth noting that, fresh out of the box, glass mousepads often have a distinct "oily" feel, which makes them significantly faster. For this reason, all my tests were conducted after a period of regular use. What I mean is that the second image better reflects performance under steady-state conditions; in reality, the results won't be as insame as they appear when the pad is brand new.

Preludia 「EIRA」 I mostly post about ultra-speed glass pads, and this one is no exception; it sits in the same tier as 'speed monsters' like the Jane and Apex. However, since I’m currently in the testing phase, I can only comment on the speed performance right now, I’ll save the detailed review for later. On a side note, I just reached the Celadon rank using this pad.🥳
