Banana and Ginger Bread: 7/10

My team at work decided to have a week of baking, and mark each other's creations a la Come Dine with Me. My team is four guys and one girl, so this was not expected.

I haven't baked for years, and the only thing I could think of is Marie's banana bread which she calls idiot proof. Hypothesis, meet test.

I even carefully measured out ingredients using a scale, because apparently you need to do that with baking. The recipe is something like this, I halved the quantities below to do one loaf:
Mix half a pound of butter and half a pound of sugar. I was frightened by the volume of butter and sugar here, I had no idea banana bread had such a calorific starting point.
Beat in two eggs.
Sieve the following in: 3 cups flour, 3 tsp baking powder. At this point I added two tablespoons of ground ginger, my first departure from Marie's recipe.
Dissolve 2 tsp of baking soda in a little milk, and add.
Add 5-6 near rotting bananas. At this point I added a dash of vanilla extract, my second departure from Marie's recipe.
Line tin(s) with baking paper, and pour in.
Bake in a moderate oven (I used 180 fan) until an inserted knife comes out clean. This took about an hour or so for me.

The cake tasted good, and the ginger gave it a nice little kick on the end of the palate. My colleagues seemed to approve. So why only 7/10?
I think baking really does demand accuracy of ingredient measures and sticking to the recipe (at least for a novice baker). Two skills which don't really feature highly in my cooking, I have more of a "what would happen if I added this ingredient?" approach. Which sometimes works, and sometimes doesn't.
Even though I tried to measure ingredients, I suspect my measuring was off by up to 20%. Electronic scales would be easier to read. And, I couldn't help adding bits and pieces (ginger) I had read on the interweb somewhere.

Maybe if there was some way to bake bread that incorporated meat. Pancakes with bacon and banana and maple syrup work, so maybe banana bread could be adulterated with bacon.
