```Hi.

I=B4ve been developing a online "Interactive Time Travel" for some time, P
and S tables works pretty close (need to tune up somethings)..but cant get
LQ and LR times match USGS Time Travel Calculator, example:

Todays Taiwan Eq, (+-) 111 deg.

My Tool:
LQ 3522s 03:02:02
LR 4025s 03:10:25

USGS

LQ 2824.90s 02:50:24
LR 3135.24s 02:55:35

I=B4m using P.jb, S.jb, LQ.jb and LR.jb tables found in WinQuake, if i go t=
o
the LQ.jb table and locate depth:20km ; 111deg, i found: 3494s, which is
pretty close to my tool, but far for USGS results (and realistic results), =
to
match USGS results i=B4ve to look to 90deg corresponding to 2827s.

Does LQ.jb and LR.jb tables differ from P.jb and S.jb tables?
Does anyone have clue where can be the problem?

Best Regards,
Tiago.
