From the perspective of actual capability improvement, at each stage, a Mechanical Warrior can clearly perceive some changes.
For example, at the First Level, apart from the continuous increase in the power of operating the War Armor, as the Brain-Machine Synchronization Rate increases, the synchronization delay time will gradually shorten, shrinking from the initial 35 milliseconds standard value, continuously reducing until the value overall decreases by 10%, reaching around 31.5 milliseconds.
If you use an amplifier, the delay time will extend to a bit over three times.
When Ren Zhong used the amplifier, he perceived a delay of 100 milliseconds, while his actual delay was 33.33 milliseconds at that time.
