Steady drive or P&G for best FE with AC?

I had AC clutch coil failure some time ago, and didn't bother to get it fixed. Now with summers making me pant like a dog, I had to get the repairs done with no choice.

After the AC switch ON, I try to do Engine ON coasting - this had not been much of a problem earlier bug earlier I had not been observant enough. Now I feel that with my 67 BHP vehicle, I am not getting good FE with Engine ON coasting, with th Speed-up/coast-down approach The acceleration is taking too much fuel now, that the AC load is also always ON. If drive on with very light right foot, I can get better FE than I can by engine-on-coasting.

What is going wrong? Is what I see logical?
