Instead of everyone speculating, the following is is the scorecard for the routing shown.
Note that the routing is anything but finalized at this point, and we might not build every back tee listed. However, the tees shown are in most cases the longest the hole could play without moving earth to put a tee further back - which I almost never do. Here goes:
Front 9: 365, 440, 450, 310, 145, 240, 360, 435, 440
Back 9: 215, 380, 175, 375, 160, 470, 395, 295, 400
To me, that's not an excessively difficult course, but certainly not a pushover either. Please note, I am not inviting people to analyze this and tell me I need a hole between 400 yards and 435 so you will hit a 6-iron approach. I'm just trying to give you a sense of what a 6,075-yard par 67 course actually looks like. We could still make it a 7000-yard course if I changed holes 9-14, and used more land; I'm not going to go that far, but we're not stuck on par-67, necessarily.
Just for comparison, Swinley Forest:
Front 9: 389, 367, 290, 184, 497, 424, 400, 146, 434
Back 9: 205, 285, 455, 174, 366, 493, 415, 170, 368
Pulborough:
Front: 484, 412, 367, 383, 158, 226, 441, 185, 367
Back: 395, 458, 221, 382, 458, 145, 369, 461, 443
and Rye:
Front: 481, 180, 437, 411, 165, 468, 159, 391, 300
Back: 420, 324, 420, 430, 184, 458, 419, 222, 439
Yes, Rye is as hard as it sounds when you look at it that way. And it adds up to 6308 yards! The one "pushover" in that card, #9, is actually the hole on Ran's homepage right now.
All of these cards were handy because they were all printed in the front of The Confidential Guide. I didn't even realize I had picked all three courses for the Gourmet's Choice back in 2014. It's been a long campaign
