Quarterly/YTD Calculation

Hello! I need assistance creating a calculation (in a new table) based on data in a Pivot table to Sum quarterly (Year-to-Date) counts of Actuals IF we've reached the end of a particular month, as such:

PIVOT TABLE
MONTH/YEAR AAA BBB CCC Grand Total
18-Nov 1.1 8.8 3.3 13.2
18-Dec 2.2 7.7 4.4 14.3
19-Jan 3.3 6.6 5.5 15.4


In another Table, I want to (automate) the Quarterly percentage of ACTUAL headcount not Forecast (although populated) only IF we've reached EOMonth by Dept:
1Q = Nov/Dec/Jan 2Q = Feb/Mar/Apr 3Q =May/Jun/Jul 4Q =Aug/Sep/Oct, and Fiscal YTD.
In other words, I only want to Sum counts for Nov thru June but update/include July numbers once they become Actual. 4Q should remain Blank until Aug numbers are reported after Aug 31st. To that end, I was trying to create a SumIF or SumProduct/EOMonth/RoundUp statement/formula to group the data (%) by Quarters and Fiscal YTD but couldn't get it to work.

NEW TABLE/END RESULT
TYPE 1Q19 2Q19 3Q19 4Q19 FY19YTD
AAA 10% 20% 10% 20% 40%
BBB 20% 30% 20% 30% 70%
CCC 30% 15% 30% 15% 75%


FORMULA USED:
=SUMPRODUCT((ROUNDUP(MONTH($B$5:$B$7)/3,0)=ROWS($C$5:C5))*$G$5:$G$7)

Thanking you in advance for your time and consideration.
