Question how to read next records

Hello friends,
I am newbie in programing. I am facing some problems in awk. Please help me.
I have a file with many data sets. Each data set is separated by an empty line. For example
Col1 Col2 Col3 Col4 Col5
0.85 0.07 Fre 42:86 25
0.73 0.03 frp 21:10 28
0.64 0.04 Fre 42:86 63
0.47 0.08 nie 25:76 32
0.37 0.01 veb 00:71 26
0.63 0.48 Fre 42:86 65
0.65 0.32 frp 21:10 19
0.47 0.08 nie 25:76 43

0.53 0.56 nie 25:76 52
0.32 0.43 veb 00:71 18
0.85 0.07 Fre 43:86 40
0.65 0.32 frp 21:10 30
0.85 0.07 Fre 43:86 50
0.53 0.56 nie 25:76 20
0.65 0.32 frp 21:10 40
0.85 0.07 Fre 43:86 50

0.85 0.07 Fre 43:86 60
0.32 0.43 veb 01:71 30
0.32 0.43 veb 01:71 80
0.65 0.32 frp 21:10 40
0.85 0.07 Fre 43:86 70
0.53 0.56 nie 25:76 60
0.65 0.32 frp 21:10 50

In this data Col4 is primary key.I want to check that if Col5 value is increasing for a specific record in first data set.If it is true for some records(as for "Fre 42:86 25/Fre 42:86 63/Fre 42:86 65" and "nie 25:76 32/nie 25:76 43") then read the next data set and check if the Col5 value for these records(Fre 42:86 and nie 25:76) is greater than 30. If true then just count it.So all the values in Col5 for "Fre 42:86" is greater than 30 but not for "nie 25:76" as there is one record "nie 25:76 20" and it's Col5 value is less than 30.Therefore I have 1 count for first data set.
Similarly then I should check the second data set that if Col5 value is increasing for a specific record in second data set.If true then read the next(third) data set and check if Col5 value for those records is greater than 30.If true then just count it and so on.
Please if anyone can guide/suggest/help me in solving this problem.
Thanks in advance.

tracker-info - Retrieve all information available for a certain file. SYNOPSIS
tracker-info [OPTION...] FILE... DESCRIPTION
tracker-info asks for all the known metadata available for the given FILE. Multiple FILE arguments can be provided to retrieve information about multiple files. The FILE argument can be either a local path or a URI. It also does not have to be an absolute path. OPTIONS
-?, --help Show summary of options. -V, --version Print version. -f, --full-namespaces By default, all keys and values reported about any given FILE are returned in shortened form, for example, nie:title is shown instead of http://www.semanticdesktop.org/ontologies/2007/01/19/nie#title. This makes things much easier to see generally and the output is less cluttered. This option reverses that so FULL namespaces are shown instead. -c, --plain-text-content If the resource being displayed has nie:PlainTextContent (i.e. information about the content of the resource, which could be the contents of a file on the disk), then this option displays that in the output. -t, --turtle Output results as Turtle RDF. If -f is enabled, full URIs are shown for subjects, predicates and objects; otherwise, shortened URIs are used, and all the prefixes Tracker knows about are printed at the top of the output. SEE ALSO
tracker-store(1), tracker-sparql(1). http://nepomuk.semanticdesktop.org/ http://www.w3.org/TR/rdf-sparql-query/ GNU
