I do not see what tail gives you. But. Try this.
You may want to learn about the sync command, and how new data is written to disk periodically, not continuously.
Since the kernel keeps all of the data being written to outfile, tail -f will see it all (except the first 990 lines of outfile)

mtail
MTAIL(1) User Commands MTAIL(1)NAME
mtail - tail variant designed for web developers monitoring logfiles
SYNOPSIS
mtail [options] <file>...
DESCRIPTION
MonkeyTail allows a user to tail multiple files on both local and remote hosts and clearly marks inactivity by putting 5 newlines in the
output whenever a pause in output over 3 seconds is detected.
MonkeyTail is implemented a fairly simple wrapper script around standard tail, ssh, and sudo.
OPTIONS -q Quiet mode
--quiet
" "
-n Output the last N lines of each file before tailing (defaults to 0)
<file>...
Files to tail.
These can specified in the following ways:
@<groupname>
- expands the group (from .mtailrc) to a list of
files to tail
<filename>
- tails a local file.
+<filename> - attempts to sudo and tail a local file (will
prompt for pwd if required).
<remotehost>:<filename>
- attempts to invoke tail via ssh on a remote
host.
+<remotehost>:<filename> - attempts to invoke sudo tail via ssh on a
remote host (will prompt for pwd if required).
