TS , if your veloviewer stats are for real, you should have no problem with PBP.
In an Arrivee article in 2011, Tom Jackson reckoned 5000 miles between Jan 1st and PBP was enough to prepare for what was to come.
Obviously qualifying does take time and effort but go for it.
If you can get to the FFCT Semaine Federale in the next year or two , then that will give you a small taste of what awaits at PBP.
