GP2 - discepancy in track length, 99 track pack

I have downloaded the 99 trackpack from alphaf1.com. I am curious about the track length parameter in GP2 and would welcome any explanation of it. The original GP2 for example gives Silverstone 94 as having a track length of about 1300, however the 99 track pack gives Silverstone 99 as having a track length of 5.xxx. What units are these values in? What does this parameter actually represent? Why is there such a discepancy? Thanks in advance, mart -- Mart Hugh Rogers

Where did you get the "1300" value? In the trackeditor? Than that's probably the number of traklengthunits that the track consists of, including the pitlane. One unit is 16 feet, is 4.87 meters. The 99-trackpack has about the same number of tracklengthunits, but I guess you looked at a different value, which gave the calculated length in meters, Silvy is about 5kms long.

Yes, in the track editor. Am I supposed to enter the value as km or trackunitlengths? Is it normal to have to convert this, why would the value be given in km if its intended use was to be set via a trackmanager - as the trackpack is I believe. Thanks. mart

The tracklength is also given in kilometres in the same stats window, called "length km: track" I don't know where you would want to enter this value (some trackmanager or whatever?) so please explain. I don't know anything about the trackmanager, but the trackpack is, IIRC, intended to be installed stand-alone. Read the TXT file in the trackpack to be sure of the installation.

Thanks for your reply. From the install file tpack99.txt (step 6)... "Note! * The original GP2 track names, circuit pics, number of lap data, circuits lenghts and tyre consumptions do not match with the '99 ones, so you must change them." This is what I am attempting to achieve using WinTrackMan. Am I missing a trick here? Thanks mart -- Mart Hugh Rogers

I see. (I never used this trackmanager, so forgive me for not putting the things together) Dug up my trackpack, found the folowing table in there (see below): I guess all values are in there. I guess you have all values now, everything clear? Or do you need to know more, other stuff? Circuit Date Laps Length Tyre C.

Well actually I have two points of confusion : 1. Does it matter what units the length is entered in - GP2 appears to use 16 foot trackunit lengths, and trackpack99 uses km. The trackmanager field is either a textual string which doesn't care about the value, or it relies on some units being input. 2. Is the length of the track or the number of laps used to calculate the length of the race/amount of fuel installed. Are these values the same as the ones I might edit from GP2Edit. I guess what I am lacking here is knowing in what files the datasets are stored in and what tool edits which files, and in what circumstances data values can be held in more than one place and overridden - like the name of the track may be hardcoded in some GP2 file, or can be extracted from a f1ct??.dat file Any good background for this kind of info? Many thanks for your time. Mart -- Mart Hugh Rogers
