Please actually research optimism bias first - it applies to the way any management team develop projections.
GMC stated 4 milestones for December 2017, none were hit - you could argue due to their optimism bias.
So using GMC's projections (not mine, there's a difference that I'm not convinced you appreciate), as stated in their quarterly they run out of cash by 31 March 2018.
Adjusting for optimism bias, means they will likely run out sooner than they anticipated, in the same manner that the milestones are never delivered.
But let's just stick to what GMC have told us
Cash will be nil by 31st March 2018.
