Good.

No. 

For any REAL circuit, you figure 50% of input power, since there are so many losses in the 
circuit you cannot calculate for, nor even find. In addition, even your INPUT power reading 
isn't 100% accurate either.

45 watts output for "90 watts" input is just fine.

There is nothing at all to worry about here.
