What a fuking joke. This moron dives into research that MUST uses base line studies to compare modeling on the REAL round world. Base lines are litterally, if the 'base' was flat - here is what would happen. But because the Earth is round, here is the effect... so stupid these people.

0.17: the report says right below: 'the need for linear models is...'
0:21: a dissertation from a student using a 'flat' model to prove a therory 0:22: they give three examples, the first flat, for the baseline, then round, etc. 0:25: modeling base-line for comparison.
