[mrtg] log file format

[Mitchell K. Smith]

I need some help understanding the log files.
Using version 2.9.25.

Here is my example.

This is from the Daily 5 min. average graph:
Max  In: 3286.9 kb/s (7.3%)   Average  In: 407.4 kb/s (0.9%)   Current  In: 1052.3 kb/s (2.3%)  
Max  Out: 649.0 kb/s (1.4%)   Average  Out: 270.9 kb/s (0.6%)   Current  Out: 267.6 kb/s (0.6%)  

This is the log file for this interface at the same moment:
7206-inet.ems.net_hs1_0.log
1035319516 3949071763 1414454502
1035319516 119757 32410 119757 32410
1035319215 218534 67324 218534 67324
1035319200 208189 65196 218534 67324
1035318900 56503 35069 79626 58844

According to the log file format documentation,
D (4th column)
The maximum incoming transfer rate in bytes per second for the current interval. This is calculated from all the updates which have occurred in the current interval. If the current interval is 1 hour, and updates have occurred every 5 minutes, it will be the biggest 5 minute transfer rate seen during the hour. 

E (5th column)
The maximum outgoing transfer rate in bytes per second for the current interval. 

Can someone explain the math for this.

Thanks for your help.
