Count last 3 results only

I have a table of results and would like to check the last 3 known positions across a row of data excluding a few columns and provide an answer on the results if finishing in 1st or 2nd place.

Sample spreadsheet enclosed

Answer / formula required in column "Q"
Look for the last 3 results in each row counting backwards and excluding columns "H" and "P"
and if either a 1st or 2nd place then show "0" any result which is 3 or higher in last 3 results then show "1"

Thanks in anticipation.
