Dyno load cell 'co wogas' cannot be used in press tests because the

'dyno gas force' and 'calc gas force' do not match 'dynamic gas force'.

[i.e.  there are 3 diff gas forces]

For press tests, 'co wogas' eliminates gas by using c+ca+drag.

Therefore, 'co wogas' will differ between 'Sh Dyno' and 'Sh Dyno . press targ'
