There are formulas used in the industry to determine if the subfloor has excessive `deflection` [bounciness. lack of rigidity]. The most cited one is the Tile Council of North America standard for deflection. which is stated as L/360 as a minimum. before tile underlayment is installed. L/360 means that the floor should not bend under weight more than the length (expressed in inches) of the unsupported span divided by 360. For example. if the span between supports runs for 20 feet then the deflection should not be more than 2/3" between the center and the end. L=20 x 12" = 240". L/360 = 240"/360 or 2/3". So 2/3" is the maximum amount of movement the center of the span should be allowed to move.

What condition does the wood appear to be in? Even if the amount of wood support seems adequate according to the tables. if it appears to have been water damaged. if sections of it look moldy or corroded due to rot or decay. it`s not doing its job. Options include replacing or reinforcing it. but not just ignoring it. Also. has it been cut into in various spots. such as a plumber cutting sections of the joists for positioning pipes? All of these problems can make the wood less effective.
What floor covering was on the floor before? If it had ceramic tile or stone. and the floor received reasonable traffic for years with no cracking or broken grout. it`s a pretty good bet that the subfloor is up to the job. If it was vinyl. carpet or hardwood. we are still in the dark.
