Editing Lap time and delta analysis (section)

== Sector attribution (worked method) ==

1) Compute <math>\Delta T(s)</math> and mark sector endpoints <math>s_k</math>.  

2) Sector deltas are differences of the cumulative curve: <math>\Delta T_k=\Delta T(s_k)-\Delta T(s_{k-1})</math>.  

3) Within a corner, split phase deltas by integrating only over the corresponding ''s'' intervals (entry / mid / exit).  

4) Attribute mechanisms by co-evaluating <math>v,\,a_x,\,a_y,\,\mathrm{brake},\,\mathrm{throttle}</math> traces and, where available, power and platform proxies.
