Overwatch PNG, RTT and IND: How they affect gameplay experience

On PC, when Ctrl–Shift–R is pressed, PNG, RTT and IND appear. I suppose PNG stands for ping. What do RTT and IND mean, and how do they translate to gameplay experiences?

Are the numbers related like for example PNG = RTT + IND?

By that I mean to ask, what happens when:

• PNG > RTT > IND
• PNG > IND > RTT
• RTT > IND > PNG
• Etc. (Provided they obey the math relationship between them)

Is there a meaningful reflection of these numbers in terms of gameplay experiences?

I.e. which combination(s) causes gameplay experiences such as:

• Landing a hit on the opponent in my perspective, when the opponent is already behind cover in his.
• The opponent landing a hit on me in his perspective, when I'm already behind cover in mine.
• Etc.
