That's certainly not the way you usually express thrust to weight ratio - usually it's T/W, which routinely gives a number below 1.0 unless you're a fightery type thing.
The next thing to watch for is that the thrust used is the "static thrust" - the force that the engine provides at zero airspeed. That force drops off quite quickly with airspeed, so the "real" T/W at the end of a takeoff run may be noticeably less. There's also increased drag on the aircraft, further reducing the acceleration.
Finally, will two aircraft at the same T/W have the same performance? No. Because they may have very different takeoff speeds, so despite having the same acceleration, if one takes off (to be extreme) at 100 knots and the other at 150knots, the second one will need 2.25 times the runway of the first one (roughly).
(Furthermore, much takeoff performance is actually based on the "what if" case of an engine failure. Losing one out of four is different to one out of two, obviously. Looking at the OEI (one engine inoperative) T?W values may in some cases be as meaningful...)
