You've got a typo in the second row (V1 column).

Yes, here is the corrected table:

Notation:
Vo volts measured when I is zero (switch off)
V1 when switch is closed (I as indicated below)
I current measured current (switch on)

1) Results for R1 (nominal 2.8 ohms, 12.3A)
Vo=6.0 V1=4.2 I=1.33 A
Vo=10.0 V1=7.2 I=2.39 A
Vo=16.0 V1=11.7 I=4.00 A
Vo=20.0 V1=14.7 I=5.06 A

2) Results for R2 (nominal 21.5 ohms, 4.4A)
Vo=6.0 V1=5.5 I=0.24 A
Vo=10.0 V1=9.3 I=0.42 A
Vo=16.0 V1=15.0 I=0.67 A
Vo=24.0 V1=22.7 I=1.03 A
Vo=30.0 V1=28.3 I=1.28 A
