FWIW the mLido depiction of the CLN 1E not unsurprisingly agrees with the Jepp - SSE23 at 5000, SSE26 at 6000 with 3.0 miles between the two..but as you say comfort..what's that?
Going back to the OP - mLido also has in text on the chart : "Warning - Stepped Climb..Due to interaction with other routes pilots must ensure strict compliance with the specified climb profile unless cleared by ATC"
