Are you starting to see the importance of being concise in your explanations, especially in instructional situations.
Correct use of technical jargon.
And avoidance of "double use". You say
the NR decay decreases.
Do you mean the NR is still reducing, but decreasing at a lower rate? (I suspect you didn't mean this.)
Try phrasing the complete question again.
You can see there are pleanty keen to help.
