It is not clear what you mean with diff value, is that field 6 or field 10. Also is the difference only >10 or also <-10 :
Here is an example you could try with $6 and both negative and positive, to give you an idea of how this might be approached:

Code:
$ awk '$1=="Comparing"{p=$0} $1=="Line" && ($6>10 || $6<-10) {if(p){print p; p=x} print}' infile
Comparing csv_converted_files/0520/7447.1012H67126.5077292103609547345.csv and csv_converted_files/22004517/97447.1012H67126.5077292103609547345.csv

cpc_event_accum

cpc_event_diff(3CPC)													      cpc_event_diff(3CPC)

NAME

       cpc_event_diff, cpc_event_accum - simple difference and accumulate operations

SYNOPSIS

       cc [ flag... ] file... -lcpc [ library... ]
       #include <libcpc.h>

       void cpc_event_accum(cpc_event_t *accum, cpc_event_t *event);

       void cpc_event_diff(cpc_event_t *diff, cpc_event_t *after, cpc_event_t *before);

       The  cpc_event_accum()  and  cpc_event_diff() functions	perform common accumulate and difference operations on cpc_event(3CPC) data struc-
       tures. Use of these functions increases program portability, since structure members are not referenced directly .

   cpc_event_accum()
       The cpc_event_accum() function adds the ce_pic fields of event into the corresponding fields of accum. The ce_hrt field of accum is set	to
       the later of the times in event and accum.

   SPARC:
       The function adds the contents of the ce_tick field of event into the corresponding field of accum.

   :
       The function adds the contents of the ce_tsc field of event into the corresponding field of accum.

   cpc_event_diff()
       The  cpc_event_diff()  function	places	the  difference between the ce_pic fields of after and before and places them in the corresponding
       field of diff. The ce_hrt field of diff is set to the ce_hrt field of after.

   SPARC:
       Additionally, the function computes the difference between the ce_tick fields of after and before, and places it in the corresponding field
       of diff.

   :
       Additionally,  the function computes the difference between the ce_tsc fields of after and before, and places it in the corresponding field
       of diff.

       The cpc_event_accum() and cpc_event_diff() functions exist for binary compatibility only. Source containing these functions will  not  com-
       pile.  These  functions	are  obsolete  and  might  be  removed	in  a  future  release.  Applications  should  use  cpc_buf_add(3CPC)  and
       cpc_buf_sub(3CPC) instead.
