It to late now, but for the amount of mixing you have done over the last year, did you think on getting a mixer? I bought a secondhand one when laying 60m2 of slate patio and then sold it in after for pretty much the same price. It seems to be fairly common for people to do this.
Mind you, with all that mixing by hand you are getting a free workout.

I find if I use the mixer the mortar is starting to go off before I can use it all because I'm so slow at laying bricks and blocks
A barrow full of hand mixed mortar is the perfect amount for the speed I work at and probably takes less time than getting the mixer out, cleaning it and putting it away again 😄
It'll be worth it in the end
