Sizing radiator steam traps

in THE MAIN WALL
Referring to Holohan's chart for Hoffman traps on pg. 148 of TLA, let's say that a radiator's s.f. EDR called for a 17C trap. What would the effect or result be if an 8C was instead installed?

    if replacing

    just one, try to match its capacity with a ''like'' capacity trap..if your talking in general, the radiator traps can only allow thru what the return main air vent allows..its the final orifice.

    too little = bad; too big is the same?

    I understand that a trap that is undersized limits optimal radiator steam trapping and air venting. My issue, however, is that I have an 8C on a radiator that should instead have a 17C and I want to know whether it is a problem. Neither Holohan's book nor online Hoffman literature addresses this issue. Is it screwing up trapping and venting performance?

    Additionally, most of my radiators have Trane B1 traps. They range from 1/2" to 3/4" size in either angle or vertical configuration. I would appreciate knowing where I could find a Trane Capacity Table for these traps similar to the chart on pg. 148 of Holohan's TLA.
