Well hopefully the player uses the same fingering system as the person who wrote the chart. I use one finger per fret on Bass Guitar and Simandl (1,2,4) on string bass, so my fingering and shift patterns would be totally different depending upon which instrument I was playing.
Some people play bass guitar with 1,2,3 or 1,2,4.
There is also a bass guitar fingering system that uses four fingers that is not one finger per fret. Microshifts are uses to avoid hyperextending the hand, so you might see 1,2,3 or 2,3,4 but not 1,2,3,4. This sets up a totally different finger pattern and series of shifts than one finger per fret.
Even string bass players who use Simandl tend to choose different finger patterns and shifts.
I am really not trying to be disrespectful, rather I am trying to illuminate why I think it's not as universal of an idea as you might think.
IMHO Fingering is really a matter of pedogogy rather than something that should be looped into sight reading training. Sight reading should focus more on note recognition in the context of standard notation, and on the ability to improvise a line when presented with chord notation.
