Please re-check the manhours for Yard 1 & 4 on 2nd March 2015.
Manhours for direct and indirect are 1880 and 168 respectively with 320 direct men and 44 indirect which averaged out very low compare to 8 hours of work.
Note that this manhours are also same as the numbers reported on 1st of March, probably a case of wrongly copy and paste.
Next, please check on the overtime on Yard 5 direct men. From the start till now, all the direct men are working at exact 5 hours per day for each person. Please verify that this data is correct as all these manhours should have the actual fingerscan date to verify.
