Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_50059 ( "Year" real, "Starts" real, "Wins" real, "Top 5" real, "Top 10" real, "Poles" real, "Avg. Start" real, "Avg. Finish" real, "Winnings" text, "Position" text, "Team(s)" text )

### Question ###
What was the highest number of starts in 2007 when the average start was over 17.6?

### Accurate SQL ###

SELECT MAX("Starts") FROM table_50059 WHERE "Year" = '2007' AND "Avg. Start" > '17.6'
