Question about output stage

I want to implement this output stage

but i want to use it as class A amplifier and not as AB class. If i use it as class A, all mosfet are on during 2pi period of sinusoid, so Ioutmax is equal to 4Iquies. But if i calculate efficiency, i obtain this result

What's wrong? Thanks

** Nonsenese.

I out max = 2 x I quies.

At full sine wave output, current in each mosfet varies from zero to double I quies.

Max efficiency =50 %.
