-- Added `checkpoints` logic for calibration, to skip parts of the graph that are already good to go
+- Added `checkpoints` logic for calibration, to skip parts of the graph that are already good to go.
+  This diagnose of the checkpoints starts from the first ones, until finds the first in each branch, that doesn't pass.
 
   Example:
 
   If \[i\] are notebooks and \[V\] or \[X\] are checkpoints that pass or not respectively, in a graph like:
 
-  \[0\] - \[1\] - \[V\] - \[3\] - \[4\] - \[X\] - \[5\], calibration would start from notebook 3
-  \[0\] - \[1\] - \[V\] - \[3\] - \[4\] - \[V\] - \[5\], calibration would start from notebook 5
-  \[0\] - \[1\] - \[X\] - \[3\] - \[4\] - \[.\] - \[5\], calibration would start from notebook 0
+  - `[0] - [1] - [V] - [3] - [4] - [X] - [5]`, calibration would start from notebook 3
+
+  - `[0] - [1] - [V] - [3] - [4] - [V] - [5]`, calibration would start from notebook 5
+
+  - `[0] - [1] - [X] - [3] - [4] - [.] - [5]`, calibration would start from notebook 0 (Notice that the second checkpoints is not checked, since the first one already fails)
