My question is: what's the best algorithm for constrcting broadband access record from radius accouting packets?

They should yield (approximately) the same result. But, to be pedantic, you haven't accounted for latency within the network.
Somebody should be whipped, either for: 1) If you can find a network where that matters, even in the slightest, the oerson responsible for the design and/or maintainance OR 2) You, for making even this aged arch-pedant wince. :-) Seriously, can I also add that RADIUS interim accounting is almost essential in this scenario. Real world accounting and session boundaries mis-match badly making it almost mandatory to use interim accounting records to get an approximation of what the figures look like from a billing perspective. I'll also add "watch out for missing records" - I've found RADIUS to be the lossiest network protocol per foot of cabling that I've ever used.
