Default Laguna Qual Lap Video

Since it was talked about in the other thread I cut out a qual lap from the last race of the last season at Laguna. Best qual lap was 1:37.4 but the one in the video is a 1:37.9 that I did earlier in the same session. I didn't get video because I ran out space on the CF card.

Below is a plot from my dl-1 showing the differences between the lap on the video and the best lap of the session. Data shows best theoretical at 1:36.8

Ry, I am unfamiliar with "best theoretical" feature. Can you tell me how that is approximated and how to interpret the color coded plots you posted?

the DL1 software splits the track into segments and then adds together the lowest time for each segment. For laguna they have 9 segments. I let the software auto-pick them

On the time slip graphs cyan is no time lost with red being the most time lost.

If you look at the first graph I posted the 3rd row is time slip. The bottom of the graph would be best theoretical and as the black or red lines move up the graph I was losing time there.

btw hard to say since I don't have video but its probably likely I passed a car(or two) going into T2 and thats why there was time loss thru that sector.

huh?

I usually judge how I did based on how close I'm to the theoretical best. I try to stay w/in a .25 second of it. In this case I failed, but does mean I should have no problem doing :36s with the current setup.

If you don't catch Kip in the white car I will be surprised in 2008.
