Sorry André; the example was meant to be more illustrative of the curve process than a fixed curve.  Yes, I would start at a lower setting and work up until you find what coats the paper smoothly.  I found papers to differ greatly in how much glop they will absorb without puddling.  If you have a channel dedicated to glop in your inkset (I am not using the UT14) you can print a curve that puts glop only in the highlights during the first print which may also allow you to lower the over coat if one is needed  I use something like 0;80 10;26 30;0 100;0  to lay heavy glop in the highlights then taper off to nothing by 30%.  This works for gloss differential but won't work for mid-tone bronzing if that is an additional problem.  For that you will need a second coat and that will vary paper to paper.

I'm also think we'll find that the GLOPs vary quite a bit.  I initially used some epson glop with good results, I then switched to MIS glop which didn't seem to cover as well.  I have some new Epson Glop that I am going to put back in and give it a try now that I am more familiar with the inkset I am using.  I was looking at the piezography  forum and they are starting to do  overcoating for glossy papers.  It looks like they have designed their own glop formula and in over coating they are using a dedicated glop printer with multiple channels to get smoothness while lowering the glop level.  Makes sense.
