Solid Hardwood, Engineered and Laminate Flooring - Where to put the final cut-plank row?

I hope to install a Pergo Presto floor this weekend. Subfloor is prepared. The most visible wall in the room has a baseboard radiator running along it. The opposite wall is next in line in terms of visibility.

As a general rule, installation should begin at the most visible wall with a full-plank row. However, given the presence of the radiator, can I begin the installation at the opposite wall (2nd most visible), and finish up with a cut-plank row under the radiator? What good is a full-plank row if a good part of it is hidden under the radiator?

My only concern with this approach is that it will be a challenge to scribe the cut exactly to the .25" expansion gap with the radiator in the way. Will I ruin the installation, if I make sure that the gap is as close to .25" as possible and if I err, make sure that the gap is slightly larger than .25"?

A couple of thoughts: try not to have a plank width that is less than a 1/2 plank for stability reasons. This might be accomplished by measuring the room and starting with a cut plank as well as ending with one. That thought only applies if you would otherwise end up with a very narrow plank. Check the expansion potential of the HDF board in the particular Pergo product you plan to install. The Presto appears to be a more dense board than other Pergo lines and as a matter of fact is different board made in a different factory and is not even made in the same country as other Pergo products. Most brands have expansion potential of 1/32" in 1 foot or for 20' this; 20/32" = 5/8", a 1/4" gap is clearly not enough. Wider moldings allow for wider gaps. Most dimensional change is in the form of expansion due to moisture being added but remember the planks can also shrink when calulating molding width to cover the gap.
