Diagnostic data - meaning

When reading diagnostic data from DW3000 (nucleo baord), I get the following:
DIAGNOSTICS: ipatovPeak: 1551917909, ipatovPower: 64, F1: 15544 , F2: 25412 , F3: 24241, ipatovFpIndex: 47288, ipatovAccumCount: 103

My questions are:
Why all the F1, F2 and F3 are less than ipatovFpIndex? I expected they are around ipatovFpIndex
What is the difference between ipatovPeak, ipatovPower?
What does ipatovAccumCount means?

Thank you in advance for your replay
