how to use excel's AND function in array formula?

I have this formula which goes through a lengthy list (F$13:F$5659) and gives me the largest number of concurrent cells that are greater than some number(>=$A$2). That seems to work fine for me however, I need to take this formula and add a second condition i.e. the cell must be a number. Notice that it is an array formula.

Works: {=LARGE(FREQUENCY(IF(F$13:F$5659>=$A$2,ROW(F$13:F$5659)),IF(F$13:F$5659<$A$2,ROW(F$13:F$5659))),$C2)}

Doesn’t Work: {=LARGE(FREQUENCY(IF(AND(F$13:F$5659>=$A$2,ISNUMBER(F$13:F$5659)),ROW(F$13:F$5659)),IF(F$13:F$5659<$A$2,ROW(F$13:F$5659))),$C2)}

Also Doesn’t Work: {=LARGE(FREQUENCY(IF(ISNUMBER(F$13:F$5659),IF(F$13:F$5659>$A$2,ROW(F$13:F$5659))),IF(F$13:F$5659<$A$2,ROW(F$13:F$5659))),$C2)}

I think it is because the output of AND is true or false where I need it to be an array. I can seem to get around this data type mismatch. Do I need to be changing the bins on my frequency formula? I think I’ve reached the limitations of my ability in excel and have just lost my patience for the day, please help.

Similar issue with this formula, I can’t get the isnumber to behave like I want it to.

Works: {=COUNTIF(F$13:F$5659,">=1500")}

Fails: {=COUNTIF(F$13:F$5659,AND(IF(">2100",TRUE,FALSE),ISNUMBER(F$13:F$5659)))}

Fails: {=IF(ISNUMBER(F$13:F$5659),COUNTIF(F$13:F$5659,">2100"))}
