AFAIK: Incremental enlargement made sense for ancient algorithms. Bicubic directly to target size does it much better.

You set longest edge to 5100 in LR and export !?   ;)

Copy the text below & save it as a text file called AlamyRes.js (or similar) in the PS scripts folder.

open image in PS, create a new action and then run the script (under file -> scripts). stop action recording (if you saved it somewhere else ie 'my docs' go to scripts and browse for the script, it will still work just dont move it afterwards :))

now you have an action that will resize an image to exactly 48mb. If you select a group of files in bridge go to image processor you can run the action from there and resize batches of images.

#target photoshop
var targetMB=48;
var target=(targetMB*1024*1024)/3;
app.bringToFront();
docRef = app.activeDocument;
var width=docRef.width;
width.convert("px");
var height=docRef.height;
height.convert("px");
var ratio=(width/height)*1000;
var newHeight=new UnitValue(Math.floor(Math.sqrt((target*1000)/ratio)+0.5), "px");
var newWidth=new UnitValue(Math.floor(((newHeight*ratio)/1000)+0.5), "px");
var dpi=300;
docRef.resizeImage(newWidth, newHeight, dpi, ResampleMethod.BICUBICSMOOTHER);
