No, as I said before spring tension is equal, at equal scale lengths, at equal pitch, for equal thickness strings:
- 3% extra scale length (24.75'' vs 25.5'') requires ~6% extra tension.
bending up one semitone (3% higher frequency) requires ~6% extra tension.
thicker strings 0.010'' vs 0.009'' requires 70N vs 57N or extra 23% tension!
Now, what you feel when bending or fretting is not just the tension going up but more importantly the resulting sideways force from the string being off-center.
Example 0.009 E 12th fret, bending up two semitones:
- Tension goes up from 57N to 67N, sideways deflection necessary ~14mm (will be slightly more on a floating bridge) the resulting sideways force is only 5.4N
Example 0.009 E 12th fret, bending up three semitones:
- Tension goes up from 57N to 78N, sideways deflection necessary ~20mm (will be slightly more on a floating bridge) the resulting sideways force is now 9.6N
The changes in this last example are imperceptibly small, the effects of floating trem vs hardtail on this are even smaller, anyone who claims this affects feel is clearly delusional, a slight change in action will have a bigger effect.
On a floating bridge, as it rotates forward, it slightly counters the effects of the bend, so you need more sideways deflection, the necessary rise in tension is still the same, but the larger deflection means you feel more resulting force. The effect is very small, you can block the trem with the other hand to try to feel the difference.
How far it rotates depends on the number of springs and the size and number of the other strings. The floating trem also has an advantage, the locking nut means you don't have to stretch the part of the string beyond the nut, this alleviates some of the floating effect when bending.
All of this is feel, but it is not string tension, this feel is usually referred to as sponginess.
