The Alastair-Methode to implement GTD in a BuJo

The workflow Ryder Carroll discribes in his BuJo-Manual is different from a GTD-Workflow in many ways.
But an elegant method to implement a priority-context-list is possible by using the Alastair-Method in a different way: concipated as a alternative to the classical future log, this method to create a list of dates can easily be switched to a very flexible and overall view context-list.
Simply change the dates into contexts and the appointments into tasks – and voilá!
During each weekly review i copy the next actions out of my nozbe priority list into a Alastair-Context-List to gain a flexible and comfortable oberview about my tasks for next week.
