I remember a while back...
I was kind of getting ready for my first tourney (you'll see where the "kind of" comes in...). I was at that point where I was starting to feel like I was getting somewhere. I could go the whole five minute round without getting tapped by a few guys and I even got a tap or two myself. I started to think I might be getting good at this stuff. I must have had a particularly good night and my balls must have swollen to a few times their normal size because I posted something on Facebook like: "Either coach was taking it easy or I must be getting better. I went almost the whole round with him before getting tapped!"
Brief bit of background: Normally when we're rolling, it's at most about 60% or so. If you get tapped, you gather yourself together, crawl back in coach's guard, take a breath or two, slap hands, and start again. Sometimes there's a "here's why you got caught" lesson in there, sometimes the lesson is obvious; sometimes it's just some funny shit that came out of nowhere and you laugh. We also make sure to let our partners know if there's a nagging injury or something you'd appreciate them being a little cautious with.
Fast forward. A night or two after I posted that I crawled into coach's guard and got a REAL lesson. I made some comment about some little nothing aches that were bothering me and I got a very stern: "Shut-up and roll." I tried to say something and got an even sterner: "Shut the fuck up! Come on!"
I lost count of the subs VERY QUICKLY. I got ran over. I mean RAN THE FUCK OVER by a big truck with Zog on the license plate. I'd get tapped and if I took more than half a second to re-engage I got a very commanding: "LET'S GO!!!" and *bam* tapped again. Non-stop at well past my 100% for the full five minutes. I don't think coach took so much as an extra breath. I'd limp into his guard and there was a triangle waiting for me. I sat up to try to posture and got crushed right back down. I cannot articulate enough just how insane the pace felt to me. So THAT'S what it feels like to be broken...
When that eternal five minutes was over he said in a calm, almost parental tone: "That's the difference between competition and someone taking it easy on you." When the night was over he pulled me aside and gave me a good talking to. What he said wasn't intended to be private, but that's my lesson so I'll keep that for me.
I think the important part as pertains to this thread is -- don't ever underestimate your instructor. If you were fortunate enough to find yourself in a position to actually tap your teacher, file that under "I got lucky" until proven otherwise.
