Pre-Awakened: Rimuru accelerate his thoughts 1000 times faster
0.013(fastest human perception)/ 1000(mind accelerate) = 0.000013
The value 0.000013 seconds is equivalent to 13 microseconds
Which is in that massively hypersonic perception speed range
Post TDL Awakening: Rimuru can accelerate his thoughts to 1 million times faster - 10 million times faster
1 million; 0.013/1,000,000= 1.3e-8 seconds is equivalent to: 13 nanoseconds
Which is relativistic perception speed range;
10 million: 0.013/10,000,000=1.3e-9 seconds is equivalent to: 1.3 nanoseconds.
Which is in that FTL range
True Dragon/ Ultimate slime: Rimuru can accelerate his thoughts to be hundreds of millions of times faster; so there isn't a specific value
Lowest End: 0.013/100,000,000= 1.3e-10 is equivalent to: 130 picoseconds
Which is in that FTL+ range
Mid End: 0.013/500,000,000= 2.6e-11 is equivalent to: 26 picoseconds. MFTL perception speed
Higher End: 0.013/900,000,000=1.4444444e-11 is equivalent to 14.444444 picoseconds which is still MFTL
Highest End: 0.013/999,999,999= 13 picoseconds which MFTL
summary
Pre-Demon Lord Rimuru: Massively Hypersonic Perception speed
Demon Lord Rimuru: Relativistic- FTL Perception Speed
True Dragon/ Ultimate Slime: FTL+ - MFTL
