Subject: Complicated loop in powermgm.c

Complicated loop in powermgm.c

Hello,

Isn't this a little bit comlicated, or did I miss the point?

  for (i = 0; i < CHARGE_END_ZEROD; i++)
     delta += power_history[POWER_HISTORY_LEN-1-i]*100 - power_history[POWER_HISTORY_LEN-1-i-1]*100;

Is

(x2-x1) + (x3-x2) = (x3-x1) ?

So instead of the loop, a

  delta = power_history[POWER_HISTORY_LEN-1]*100 - power_history[POWER_HISTORY_LEN-1-CHARGE_END_ZEROD]*100;

will do it!

Bye, Uwe.
