Lead sheets for swing tunes aim at simplicity and clarity. They seldom have very short time values; swung 8th notes don’t need to be written in triplets (nor a dotted 8th note followed by a 16th note). A jazz musician will automatically swing 8th notes, unless they’re told to be played straight (or even). E.g. most Latin and rock pieces are played straight.
Also the structure of the tune is often enhanced by grouping the bars into symmetrical form, such as 4 bars per system. This makes it easier to follow the chart.
Most jazz musicians prefer to simplify complex chord symbols (e.g. G7b5, #5, b9, #9 = G7alt; CMaj13 = C△; Bm7b5 = BØ).
Thank you for your input.
I normally don't use such accurate notation, but in this case I think the exact timing is essential to catch the feel of the tune. The more so since the melody turns to swing mode in the solos.
