Rammed Earth not that much cheaper

I finished the rammed earth garden wall on the backside of my house compound.  I need to put a cap on.

We learned some and are learning more.

1- if mixture is too moist it sticks to the forms when removing.  it is barely wet.

2- the ramming is not with much force by about 4 passes.

3- the wall are hard

So we started on the walls for a garage/ grain store.  I am using two neighbor teenagers who have no training.  I pay 10,000 shs per formwork which is about 1m2 of wall.  40cm thick

I had a visitor architect and we went through the pricing and it only decreases cost of wall about 30% when both cement block and rammed earth are unfinished.  I thought it would be more than that.

I could decrease the width of the wall to 30 cm and maybe save 25%
