There is also an overview of Virtual Elevation to measure aerodynamics in this Hard, you ought to be able to see a difference between the loops where you were in theĭrops and the loops where you on the hoods, and to spot little bumps and dips in the road. Even with this informal test, as long as the wind isn't blowing too See whether you can come close to modeling the 'true' elevation profile by sliding theĬdA slider around. Weigh yourself and the bike and ballpark the air density. Do a loop in the drops, then another loop faster, then a loop slower then Sure you won't get hit by a car and have good sight lines. Stop signs, or an out-and-back with maybe a little dip or something in the middle. Quickie test you can do just to get a handle on what to do. Ideally, you'll want calm conditions (both in terms of wind and traffic) but here's a

The following is a brief piece of advice from Robert Chung, from a discussion on the 'This' 'month' prior and 0 is just this month.

Prior '2' is a month 2 months ago, whilst 'This' 'month' and prior '1' is last month. CHARTS I want to plot month -1,-2 and -3 how do I do that?Īssuming the chart allows you to specify a date range you can select 'This' 'month'Īnd select prior '3' to specify a month 3 years prior, similarly 'This' 'month' and
