For a newbee wide and loose straps might be fine, indeed.
But for experienced waveriders, it is more a personal matter.
I for one, HATE loose and/or wide rear straps
The front strap, yes - indeed there should always be half or one inch further distance between screws, as your foot is twisted
But for the back strap - it must not be too wide nor too lose - but should have a firm grip (IMO), so you can really perform and push or pull with force, and you will get amazing aerial options
To the O.P. it does not matter, as it will come much later, so loose straps are fine as you have to learn jibing and getting in/out etc - but would just mention this to others, as straps are not a "journey" towards strapless, nor a thing you have to live with - it is a whole other ballgame with many extra options and more power
