re:"Bannner Year...."...to one with a problem with.......maybe you should pick the fiscal year or the calender year,but not intermix both.
...IMO,Mr.Crossland was spot on in his Banner Year depiction for f.2018 ending today.
...your "since then" is linked back to another post stating "5 and 1/2 months "which uses Jan.01/18 of the calendaer year beginning, or , you may try and make a case for your "since then" referring to a hair past midnight tonight.
...again.looking forward to f.2019 as it will soon be like a new born baby leading TMG forward
