SPR Question when Raised on Flop

[PrairieMuffinKicker]

SPR is a concept that I've been vaguely aware of over the years, but I've only recently started reading about it and trying to apply to my game. Looking at this hand from an SPR perspective once I'm raised on the flop confuses me a little.

If my math is right, once villain raises all-in, I have an SPR of 1.37. According to what I've read, any SPR under 2 makes me generally pot committed. So does that mean that I call here every time with this hand?

Or is it only when I'm the one betting/raising that I need to be concerned about SPR for actions on the future streets?

(Side note - Is my flop bet too small? I'm thinking I should have been closer to pot??)
