Nothing is perfect, but which is better, EZNEC or the Cecil-Corum method

EZNEC and the Cecil-Corum method are in agreement.
How would you measure the delay through a wire
or through a coil using the following current
reported by EZNEC through a 90 degree monopole?

EZNEC+ ver. 4.0
thin-wire 1/4WL vertical 4/23/2009 8:01:44 PM
--------------- CURRENT DATA ---------------
Frequency = 7.29 MHz
Wire No. 1:
Segment Conn Magnitude (A.) Phase (Deg.)
1 Ground 1 0.00
2 .97651 -0.42
3 .93005 -0.83
4 .86159 -1.19
5 .77258 -1.50
6 .66485 -1.78
7 .54059 -2.04
8 .40213 -2.28
9 .25161 -2.50
10 Open .08883 -2.71

Exactly how does one use a current that changes phase
by 2.71 degrees in 90 degrees of antenna to obtain
the delay through anything?

Your silence on this subject speaks volumes.
