Vekke, sounds likea good method.
I tried to quantify some of my mods and failed, after 3 attempts i gave up. The main problem i had was mentioned by metrompg. Any other cars on the road even off in the far distance ahead caused variable results. Unfortunately i couldn't find a suitably long stretch of road which had no traffic at some time in the day even late at night.
Also for a modification that has a low percentage improvement (below 1%) it becomes very difficult to measure as many variables will effect measurements more than 1%.
I recommend to save yourself some time
- park a car where you plan to do your test, see how many cars go by to gauge if its worth testing on that road.
- Mark clearly on the road where you will begin measuring from and where you will stop measuring from. Can be hard in the dark to locate a generic road feature when your trying to set speed control and measure whatever else your after
- Choose a suitably long stretch of road which will show enough deviation for the expected percentage of improvement. For example for a 0.5% change expected you probably need 10km to see a clear improvement over the noise.
- Check your results as you go, if your first 2 results dont align rethink your testing method, no use doing 10 repetitions if you are just going to get useless data.
Well good luck and i look forward to seeing your data
