These numbers are strange. The drop from sleep to standby should be at least 40mA, according to the CPU docs:
Table 20.2 DC Characteristics (cont)

Sleep -- 40 70 mA f = 12.5 MHz
Standby -- 0.01 5¹ µA Ta < 50°C
Notes: 1. 50 µA for the SH7032.
How can standby mode only drop 14 mA?

I agree. Since measurements show this model actually does have a significant effect, I now approve of it.
