calculating the total from a running totalizer that resets

a computer is entering data from a totalizer into an excel spreadsheet like below: (the entries begin at the botom)
notice the totalizer reset and started counting again.
(the actual total gallons for the day would be: 572.229 +24.317)
how do I create a formula to see only the highest number in each runtime for calculation (sum)

total gallons
24.317
24.317
24.317
15.303
0.580
572.229
554.862
126.832
113.046
95.847
81.529
65.807
49.757
33.871
20.030
1.775
0.000
0.000

Hello superchill435,

I believe the below formula will work

=LARGE(A1:A18,1)

Where you would replace A1:A18 with the range in which your data is and then 1 represents the 1st largest number.

Thanks,

hey RVASQUEZ,
appreciate the help.
this returns the largest number, but I need the formula to add "all the largest numbers" if the totalizer resets and starts a second, third, fourth, etc. counting run.
any ideas??
