If you know the number of records (you said they vary, but maybe the number is known somehow), then simply "tail" the last <n> records, where <n> is the number of records (i suppose records to be lines):
If the records are multilined but with a fixed number of <x> lines for each record:
If the records for the present day are not all stored already you still might still know the number of records from the beginning which you have to filter out, leaving the non-filtered records as new. Example: 3 records per day, today is the 10th day of the month. You will have to filter the first 9 days (meaning 9*3=27 lines) and everything left will be from today.

sa1(8) BSD System Manager's Manual sa1(8)NAME
sa1 -- Generate a system activity daily data file.
SYNOPSIS
/usr/lib/sa/sa1 [t n]
DESCRIPTION
The sa1 command is a shell script used to invoke the system activity data collector, sadc. The binary sample data is collected at intervals
t seconds apart, in a loop n times. The binary sample data is written to the standard daily data file, /var/log/sa/sadd where the dd repre-
sents the current day of the month.
sa1 is intended to be started by cron.
EXAMPLE CRON ENTRY
# Starting at 8am collect system activity records
# every 20 minutes for 12 hours
# 20 minutes = 1200 seconds
# 12 hours with 3 samples each hour = 36 loops
0 8 * * 1-5 /usr/lib/sa/sa1 1200 36
# After the 12 hour period,
# collect a system activity report
30 20 * * 1-5 /usr/lib/sa/sa2 -A
FILES
/var/log/sa/sadd Default daily activity file that holds the binary sampling data. dd are digits that represent the day of the month.
